INTRODUCTION 

In the past, when preservationists were faced with 
restoring or interpreting the interiors of historic American 
buildings, the finishings and furnishing were of primary 
concern. More recently, there has been a move toward de- 
veloping a complete picture by studying all aspects of 
material culture. Understanding construction technologies 
and building systems now plays an important role in docu- 
mentation and interpretative plans. -^ In addition to offering 
a more accurate representation of an interior, the study of 
domestic technologies can shed new light on cultural atti- 
tudes and values. Despite the emerging trend of considering 
mechanical and electrical systems such as lighting, plumb- 
ing, and heating - the examination of domestic security 
measures remains completely neglected. 

Concern for personal safety and protection of property 
is widespread today, yet, this security consciousness is not 
a new phenomena. Historically, protection of property was 
provided by the use of watchmen, dogs, fences, or locks, 
among other things. Each of these, however, were subject to 
problems. Locks and fences, although valuable deterrents, 
could be breached; and watchmen, then as now, are subject to 



human failings which prevented the proper performance of 
their duties. Also, because of the expense watchmen were 
not widely used. 

During the nineteenth century the population in Ameri- 
can urban centers was growing rapidly. The first preventa- 
tive police forces were organized in an attempt to deal with 
the problems of crime and security on a public level. 
However, the variety of security options available for the 
protection of an individual residence remained limited. The 
introduction of an alarm sounding apparatus automatically to 
detect and to announce an undesired event marked the begin- 
ning of modern security systems. 

Midway through the nineteenth century security was 
electrified. By adapting the recently developed telegraph 
technology, electricity entered the home in the form of a 
local burglar alarm. The first burglar alarm to make use of 
these technologies was patented by the Reverend Augustus 
Russell Pope (1819-1858) of Somerville, Massachusetts, in 
1853. In 1858, this patent was purchased by Edwin Holmes 
(1820-1901) who began distributing the system in the New 
York City area. Holmes's Burglar Alarm Telegraph Company 
had, by 1868, over 1200 subscribers. Shortly thereafter a 
variety of other alarm companies began to market competing 
systems . 

This paper will discuss the origins and early develop- 
ment of domestic electric security systems. The alarms of 



the Holmes company, in use prior to 1876, will be the pri- 
mary focus of this investigation. Competing companies will 
be identified, and, where possible, comparisons between the 
products will be made. 

In order to understand the development of early bur- 
glar alarm systems, research using a variety of primary 
sources was undertaken. These included the examination of 
patents, trade catalogs, business credit files, and extant 
system remnants. 



CHAPTER 1 
ANTECEDENTS 

Social and Historical Context 

Security is defined, in part, as the condition of 

being protected from or not exposed to danger; or something 

3 
that gives or assures safety, tranquility or certainty. 

Absolute protection is not possible. However, environments 
can be altered so that harm or loss is less likely. Gener- 
ally there are two broad categories of security; depending 
upon the source from which the service originates -- public 
or private. Public law enforcement -- such as police agen- 
cies, jails and courts -- are community based. These afford 
benefits to the individual but in themselves do not assure 
security. Consequently, the need for private security 
exists, and this is broadly defined as all measures under- 
taken by individuals or businesses that are intended to give 

4 
protection to persons or property. 

For centuries, the lock was the standard method of 
private security. Exactly when and where locks were invent- 
ed is not known. However, by about 2000 B.C. the Egyptians 
and others were using wooden mechanical locks. Since then. 



numerous improvements in form and materials have been made, 
and today, locks continue to play a vital role.^ 

In the colonial era, methods of public security 
continued English and European traditions. The constabulary 
and marshals, who guarded the cities during the day, carried 
the burden of law enforcement. Constables directed the "hue 
and cry" to take into custody criminals and other disorderly 
persons, and they were responsible for enforcing local 
ordinances. In all these duties, the constabulary oversaw 
and was supplemented by the watch. Male residents were 
required to serve regular turns as watchmen, patrolling from 
dusk until dawn. The purpose of the watch was to guard the 
town by limiting noisy drinking, dancing, and other forms of 
unacceptable behavior. Watchmen were also charged to be on 
the lookout for fires. Despite the limited scope of these 
tasks, watchmen were ineffective -- they often reported for 
work intoxicated, slept on duty, or refused to make their 

n 

rounds . 

This unprofessional behavior, which in the colonial 
city had been tolerated, quickly became unacceptable after 
1800. In the early decades of the nineteenth century riots 
and civil disturbances shattered the tranquility of many 
major cities. Industrialization and urbanization were taking 
place concurrently. The growth in geographic size and popu- 
lations of cities was unparalleled. The substantial in- 



creases in the resident population was compounded, beginning 

Q 

in the 1820s, by a period of mass immigration. 

The number of homes and businesses worth plundering 
increased dramatically. Industrialization resulted in more 
specialized use of land. This trend, together with urban 
growth caused spatial changes in the organization of persons 
and activities within the city. The wealthy had, in the 
preindustrial society, occupied the most central locations 
of the city. Deterioration of these once fashionable areas 
-- together with the advent of mass-transit -- changed the 
class distribution. Affluent residents began moving to the 
periphery, out of the urban centers. 

The changes wrought by urbanization presented opportu- 
nity for criminals and compounded the problem of controlling 
them. In 1789 New York had 33,000 inhabitants and was pro- 
tected by only 32 night watchmen and fewer daytime consta- 
bles and marshals. By 1843, the population was estimated at 
350,000 permanent residents and 50,000 transients. The city 
employed 34 constables, 100 marshals, and 1,012 watchmen to 
serve this tremendously increased population. Although 
crime and disorder were not new, there was a change in 
perception of these issues between 1800 and 1860. David R. 
Johnson points out that "during the first three decades of 
the century, criminal behavior increasingly seemed to dis- 
turb the prevailing tranquility of urban society; in the 



next three decades, many people became convinced that crime 
was about to undermine their society.' 

Preventing crime had different meanings to different 
people. The three major categories of crime which communi- 
ty leaders wanted controlled were: professional theft, 
street crime, and illegal or immoral enterprise (drinking, 
gambling and prostitution). Various theories on how to 
encourage proper behavior and social order resulted in 
different proposals. Some critics advocated temperance, 
others thought the answer was education, either through the 
introduction of a viable and broad-based public school 
system, or through houses of refuge that would address 
offenders one at a time. All of these proposals required a 
long-term commitment to the reformation of people who dis- 
played socially unacceptable or criminal behavior. 

In the interim, the basic problem of controlling crime 
remained. Many citizens advocated a more immediate solu- 
tion: an overhaul of policing practices. They proposed that 
cities adopt the idea of crime prevention, a theory which 
"emphasized centralized direction of a large body of men 
whose collective efforts to suppress crime depended upon 
their ability to establish a pervasive, visible presence in 
all areas of a city at all hours of the day or night." 
Slowly gathering support over several decades, the advocates 
of crime prevention finally succeeded in supplanting the 
outmoded watch and constabulary. New York, in 1844, was 



the first city to establish a public police force. ■'■■^ Over 
the next several years police departments staffed with paid, 
full-time officers capable of handling the complexities of 
the evolving urban society emerged in most major American 
cities . 

The preventative approach to policing curtailed gang 
activity and reduced street crime. Nonetheless, while 
progress in these areas was certainly commendable, preventa- 
tive policing did not adequately confront the particularly 
sensitive issue of crimes against property. While a visible 
police force might act as a deterrent to the "house- 
breaker," "sneak thief," or "second story climber," it did 
little to curtail the activities of those who occupied the 
pinnacle in the criminal social hierarchy -- the night 
raider or professional burgl ar . "'■'^ In fact, Johnson remarks, 
"during the 1850s property crimes not only continued; they 
spread geographically as cities expanded, and they appeared 
to increase in number." 

The development of a comparatively anonymous and 
complex urban society was a benefit to the professional 
thief whose methods and tools had become more sophisticated. 
The thief had the upper hand in the ancient contest between 
those who stole and property owners. Given time and secrecy 
the burglar was generally successful in his desired goal. 
Consequently, the introduction of a reliable device which 
automatically detected and announced a break-in and alerted 



the would-be-thief that his actions were discovered could 
make a significant contribution to domestic security. 

Mechanically operated burglar alarm systems had been 
introduced in England in the early 1700s. These pull-wire 
alarms mechanically linked a set of chimes to a door or 
vault lock. Reportedly, a bank in Plymouth, Massachusetts, 
was the first application of a mechanical alarm system in an 
American building. A wire from the vault door ran under- 
ground to a set of bells located in the cashier's home next 
door. Although mechanical alarm systems certainly could have 
been installed in a domestic setting, no references to, or 
evidence of residential American applications have been 
discovered. Regardless, these systems could not have been 
particularly effective. Cutting the wire which connected 
the chime or bell to the lock or vault was, for the burglar, 
a simple method to circumvent these pull-wire systems. -^^ 
Wealthy property owners needed a more effective method to 
protect themselves from illusive skillful professional 
thieves. A new concept of protection, which overcame the 
limits inherent from relying on man or his mechanical sys- 
tems was necessary. 

Tel eqraph Technology 
The telegraph, which was both the first practical and 
commercial application of electricity and magnetism only 
became possible after these forces were understood and 



controlled. This harnessing of electricity as a long dis- 
tance messenger was also the crucial innovation in the 
development of alarm technology. An understanding of basic 
telegraph components is therefore essential. 

Although electricity was known for many centuries, it 
was not until the closing decades of the eighteenth century 
that man learned how to produce steady currents of electric- 
ity by chemical means. Building on the experiments of Luigi 
Galvani (1737-1798), Alessandro Volta (1745-1827), produced 
the first true source of continuous electricity -- the 
electric cell -- in 1801. A battery was created by link- 
ing two or more cells. These cells consisted of plates of 
dissimilar metals -- generally zinc and copper or zinc and 
silver -- brought together in a conducting solution such as 
a weak acid. When the upper ends of the metal plates were 
connected by a wire, a current of electricity passed from 
the copper to the zinc through the connecting wire, and from 
the zinc to the copper through the liquid. Current flows 
continuously until the battery is exhausted, unless the wire 
is disconnected, or the circuit is broken, in which case, 

the current immediately ceases; but instantly resumes when- 

1 ft 
ever the connection is remade. (Figure 1) 

Practically all early batteries were constructed of 

the same simple elements. These one-fluid galvanic cells in 

which both electrodes were immersed in the same fluid could 

produce an electric current; but because they were subject 

10

Pope, Modem Practice of the Electric Telegraph (New York, 1869), 11. 



to the defect of polarization, it was impossible to draw a 
large current from a battery for more than a few seconds 
before its power was seriously impaired. Preventing polar- 
ization would, therefore, finally render a constant current, 
enabling the cell to maintain the same strength for a long 
time . 

The difficulty of polarization was finally overcome in 
1836 when J.F. Daniell, an English electrician, invented the 
cell which bears his name. The Daniell Cell was the first of 
the so-called constant batteries which employed two liquids 
instead of one: one in contact with the zinc, and one with 
the copper plate. These batteries were not inexhaustible; 
power would diminish if the circuit was kept closed for long 
periods of time. However, these cells were more steady than 
those previously available and could be rejuvenated. 



11 



The second step towards advancing electricity to the 
status of a major social force was the discovery of electro- 
magnetic induction. Progress was rapid once scientists had 
a readily available source of electricity. In 1819, Danish 
scientist Hans Christian Oersted (1777-1851) discovered that 
there was a direct relationship between electricity and 
magnetism; he observed that a compass needle would move when 
brought near a wire in which an electric current was flow- 
ing. William Sturgeon (1782-1850) of England is generally 
credited with construction of the first electromagnet in 
1825. This device successfully converted electrical energy 
into energy in the form of mechanical motion. 

An electromagnet is produced by enclosing a soft iron 
bar within a spiral coil of insulated copper wire through 
which an electric current is transmitted. When a current of 
electricity is passed through the coil of wire, the iron 
bar within becomes, temporarily, powerfully magnetic. The 
bar will remain magnetic as long as the current continues to 
flow, and will exert its force on another bar of iron which 
is called the armature. The process by which the electromag- 
net converts electricity into mechanical motion is repre- 
sented in Figure 2. The key is raised so no current is 
passing to the coil, and the bar is not a magnet. However, 
^when the key is depressed the current from the battery, 
circulates through the coil; the core becomes a magnet, and 
attracts its armature as indicated by the dotted lines. If 

12

fron. Park Benjamin, The Age of Electricity (New York, 1888), 81. 

the circuit is broken, the armature, no longer attracted, 

2 1 
will be drawn back by the spring. 

These two discoveries -- the battery and the electro- 
magnet -- are the foundation stones of the system of teleg- 
raphy which was to develop. By 1837, several inventors used 
these discoveries and applied them to the development of a 
practical and successful telegraph. Telegraphs transmit 
information by producing intelligible signals, consisting of 
a succession of instantaneous electrical impulses. These 
signals are, by previous arrangement, intended to indicate 
the letters of the alphabet. Because Morse's system became 
preeminent, he is often incorrectly credited as being the 
sole developer of telegraph technology. 

In its simplest form, a telegraphic circuit consists 
of a contact or sending device [or key] that makes and 



13 



breaks the connection between a current source [or battery] 
and the line which carries (or conducts) the current. The 
pulses of current pass to the distant end of the line and 
activate the receiving device [or sounder] by causing its 
electromagnet to attract or release its armature so that it 
makes a clicking noise. In Morse's apparatus, the armature 
of the electromagnet on the receiving device was attached to 
a lever carrying a steel point which embossed a mark upon a 
paper strip moved along by clock-work. The duration of the 
current, and consequently the length of the noise or the 
mark was regulated by making the period of contact by the 
key short or long. Whether signals were audible or visual, 
the armature at the receiving end of the line copied the 
movement of the key at the sending end. 

Telegraphs can start with either an open circuit or 
closed circuit. If an open circuit is chosen, during the 
idle condition, no current flows in the line. Every time the 
key is moved into contact with the opposite part of the 
wire, the current passes; therefore the battery is engaged 
only when a message is being sent. In the other, or 
closed-loop system, current travels continuously in the 
line. Interrupting the current by moving the key out of 
contact with the line will produce a mimicking action on the 
receiver . 

The first commercial telegraph line in America became 
operational in 1844 between Baltimore, MD , and Washington, 

14 



D.C. -- a forty-four mile distance. Following this success- 
ful installation, the telegraph was rapidly adopted as a 
means of communication. In addition to linking distant 
communities, the telegraph could be used on a municipal 
level -- to communicate specific concerns within a city or 
town. As early as 1839, William F. Channing (1820 - 1901) 
conceived the notion of using telegraphy to transmit fire 
alarms. During the 1840s he promoted this idea to the 
public. In several published articles he urged the City of 
Boston to construct a central station fire alarm system. •'-^ 
The previous prevailing fire alarm technique of using watch- 
men in towers to detect and church bells to announce fires 
was time consuming and failed to assist firefighters in 
locating the blaze -- a major concern in any fair sized 
city. Channing proposed that the City be divided into 
districts and that signal boxes connected by telegraph to a 
central station be placed throughout each district. The 
unique signal from each box would allow the monitoring staff 
at the central station to determine the specific district 
and box from which the alarm originated. Then an electric 
impulse would be transmitted from the central station to 
cause the appropriate district bells to be rung indicating 
an alarm. Additionally, the central office could communi- 
cate the number of the box within the district from which 
the alarm originated and thereby quickly direct the engines 



15 



to the part of the district where the fire was located. 
Because it took Boston until 1851 to act on Channing's 
suggestion. New York, became the first city to enact an 
ordinance to change from a mechanical to an electric fire 
alarm system in 1847. However, the system introduced in New 
York was much less sophisticated than that proposed by 
Channing . ^^ 

Even as the fire alarm system was being perfected in 
the early 1850s, others saw additional potential for elec- 
tricity. Not only did it signal an alarm, but it could, 
without human intervention, detect the emergency that 
caused need for the alarm. Electricity was able effectively 
and automatically to carry intelligible messages and at the 
same time make all mechanical bell and chime based alarm 
systems obsolete.

CHAPTER 2 
PATENT ANALYSIS 

In an attempt to document and establish a framework 
for illustrating how electric burglar alarm technology 
[developed over time, United States patent documents were 
searched to identify the primary patents. While this search 
attempted to be thorough, it almost certainly did not iden- 
tify every relevant patent. The alphabetical section of the 
Subject -Matter Index of Patents for Inventions Issued by the 
United States Patent Office from 1790-1873 , Inclusive , lists 
the principals. Pope or Holmes, only nine times. After 
1873, the patent office began issuing yearly rather than 
cumulative indexes. Here, Holmes appears as recipient or 
assignee of a patent an additional twelve times before 
1900. Appendix A lists the twenty-one patents issued be- 
tween 1853 and 1893 with which Holmes was known to be asso- 
ciated. Only nine of these patents (appearing in italics) 
are directly related to the burglar alarm. Because patents 
were not identified for several major components of, or 
improvements to the system, it is suspected that Holmes 
owned more than these few patents. Attempts to identify 
additional Holmes controlled patents were unsuccessful. 



17 



Therefore, information provided by trade literature or

Development of the Domestic 
Burglar Alarm Telegraph 

Little is known about the early life of Augustus 
Russell Pope. Born January 25, 1819, in Boston, and educated 
at Harvard (Class of 1839; and Divinity, 1842) Pope moved 
from Kingston, Rhode Island, to Somerville, Massachusetts, 
where he was installed as the second pastor of the First 
Congregational [Unitarian] Society on November 25, 1849. He 
remained in this position until his death, on May 24, 1858. 
According to one account. Pope was a man of "great energy, 
rare talent, and more than ordinary ability. These quali- 
ties, combined with noble sympathies and heartfelt aspira- 
tions for human welfare, led him to engage in every good 
work designed to promote the well being of his fellow men. 
He entered with ardor into his parochial duties, and by his 
kindly interest won the cordial esteem of his parishioners." 
Also, it is known that "scientific investigations and the 
rural and mechanic arts engaged a large share of his atten- 
tion. "^^ 

In October of 1850, Pope drew his first plan for an 
1 ectromagnetic burglar alarm. Two successful models were 
de and he subsequently applied the apparatus to his own 



e 
ma 



18 



home in Somerville. His son Lemuel recalled, "when not 
employed in his pastoral duties he was occupied in experi- 
menting with his invention in order to make it 
successful . "^^ On October 27, 1852, Pope filed a patent 
application for an "Improved Magnetic Alarm" and on June 21, 
1853, was granted patent 9,802.^^ (Appendix B) 

An electromagnetic bell device had been previously 
patented for use in fire alarm systems, however, Pope's was 

the first application of the new telegraph technology adapt- 

9 9 
ed for use as a burglar alarm. Although it is unlikely 

that Pope's exact catalyst will ever be known, it is diffi- 
cult to imagine that he developed his system in total isola- 
tion. Somerville was located just two miles from Boston, 
which at the time was the major American center for tele- 
graphic manufacturing. Also, as the nation s premiere 
scientific center, Boston led in making all manner of scien- 
tific apparatus and "had plenty of skilled artisans, inven- 
tors, electricians, machinists, engineers -- the technologi- 
cal elite of the nation in residence. Pope, whether 
prior to, or as a result of his endeavors, knew two of the 
most prominent figures. First, Moses Gerrish Farmer (1820- 

1893), a telegraph inventor who originally met Pope in 1851 

3 2 
or 1852 and claimed to know him very well. Farmer invented 

many of the components of the fire alarm system installed by 

William F. Channing in Boston and was, until 1853, superin- 

3 3 
tendent of that system. The second figure was Charles 



19 



Williams, Jr. (? - 1908) of Hinds and Williams, (later 
succeeded by Charles Williams, Jr.), a telegraph manufactur- 
er who first became acquainted with Pope between 1848 and 
1850.^'* The workshop of Charles Williams, Jr., where Pope 
came for production of his alarm apparatus, was a place 
where electrical inventors congregated. One of only a 
handful of similar concerns in the country, this shop em- 
ployed about twenty-five men and occupied the third floor 
and attic of a building at 109 Court Street in Boston. This 
manufacturing shop served as a place where inventors could 
study telegraph technology and have their designs for elec- 
trical instruments and apparatus made to order. "^^ At that 
time Williams's and the other small mechanical shops consti- 
tuted the entire electrical industry of the United States. 
It is therefore likely that Pope's association with both 
Farmer and Williams during his development period favorably 
influenced the system he eventually patented. 

Pope's magnetic alarm was "to be applied to either a 
door or a window, or both, of a dwelling-house or other 
building, for the purpose of giving alarm in case of bur- 
glarious or other attempts to enter the same through said 
door or window." Although, operated on the same principle, 
and by the same power, that operated the communication and 
fire alarm telegraphs, this system was different in terms of 
human involvement. For the first time the burglar alarm 



20 



telegraph automatically registered an event in addition to 
announcing it . 

Pope chose to employ an open circuit system. (Figure 
3) The circuit consisted of contact switches [equivalent to 
the telegraph key] applied to each door and window, these 
were connected by concealed wires [the line], charged from a 
battery [the power source], that led to an electromagnetic 
alarm bell with a spring circuit breaker [the receiver]. In 
this arrangement the battery was connected to the bell only 
when door or window movement closed and completed the nor- 
mally open circuit. The advantage of the open circuit plan 
is that when not in use the battery is not required to 
supply current to the line. This meant there was no con- 
stant drain on the battery, which was only capable of sup- 
plying limited power. The downside in an open circuit ar- 
rangement -- a break in the line or malfunctioning contact 
switch was relatively undetectable. 

The most important feature of the system was its 
electric bell. Here the electromagnet rather than signaling 
audible or visual dots and dashes was used to activate a 
loud alarm bell. (Figure 4) The hammer of the bell is 
attached at one end to the armature of the electromagnet. 
Between the other end of the armature and the electromagnet 
is a spring circuit breaker which is connected to one of the 
battery wires and is in contact with the second battery 
wire. Opening a window or door completes the battery

circuit. As soon as this takes place -- current flows -- the 
magnet becomes charged and draws the armature towards it, 
causing the hammer to strike the bell. During the movement 
of the armature towards the magnet, it throws or moves the 
circuit breaker out of contact with the second battery wire. 
This breaks the circuit, demagnetizing the magnet and allow- 
ing the armature to fall back so that the circuit-breaker 
again comes in contact with the second battery wire. The 

contacts close again, and the cycle repeats itself for as 

37 
long as the window is open. 

After Pope was granted his patent he set about market- 
ing the system. He installed the device into several houses 
in Somerville, some without charge, so that it might be 
tested and its merits made known to the community. He 



22

advertised in several newspapers, put a traveling salesman 
into the field, and, in 1856, he exhibited his new system at 
the Fair of the Mechanics Charitable Association of Boston 
where he received a diploma and a silver medal. Although he 
installed the system in a large boot and shoe factory near 
Boston, commercial success eluded him. Pope's "duties as a 
Clergyman would not permit him to do more, and being very 
much out of health he found it necessary to dispose of his 
patent." For the rights to his patent he received $1800 in 
cash and $8,000 in notes. ^^ The purchaser was Edwin Holmes 
who would go on to pioneer the electric burglar alarm indus- 
try. 



23 



This transfer of patent rights was not, as expected, 
recorded in the patent assignment digest. Although Holmes 
reportedly met Pope in 1857, the transfer was probably 
executed in early May, 1858. On May 6, 1858, just weeks 

before his death [on May 24] Pope had applied for his 

3 9 
patent to be reissued. He believed the original patent to 

be, "inoperative and invalid by reason of a defective speci- 
fication and claim, which defect has arisen from inadvert- 
ence and mistake." The defect to which Pope refers was the 
use of the word elastic to refer to a circuit rather than 
the intended use of the word electric. Obviously, a poten- 
tial purchaser of the patent would wish to have any errors 
corrected in conjunction with a transfer. The patent 
office granted the request and reissue 566, dated June 8, 
1858, revised the patent's underlying text. (Appendix E) 

Holmes, who had been born in West Boylston, Massachu- 
setts, in 1820, had moved to Boston in 1849 and opened a 
notions store with his brother John "selling thread, nee- 
dles, thimbles and other sewing paraphernalia." (Figure 5) 
Their shop was located at 17 Tremont Row close to the elec- 
trical shop of Hinds and Williams. After acquiring the Pope 
patent rights. Holmes relocated his family and new business 
from Boston to New York. According to his son, Holmes felt 
"that all the burglars there were in the country were in New 
York."^ Holmes, like Pope before him, and most telegraph 
inventors of the day, was self-taught in electricity. 



24 




Figure 5: Edwin Holmes (1820 - 1901) Reprinted from Edwin T. Holmes, A 
Wonderful Fifty Years (1917), 9. 



The development and marketing of the Holmes Burglar 
Alarm Telegraph are recounted by Edwin Holmes's son Edwin T. 
Holmes in A Wonderful Fifty Years . At first, sales orders 
were slow; to most people electricity was still a foreign 
concept. And, "business men were loath to believe that a 



25 



bell could be rung in the second floor of a house, at the 
opening of a door or window in the basement . "'^■^ In order to 
gain believers. Holmes constructed a model house with an 
alarm, which he carried to prospective clients as a means of 
demonstrating how the system worked. (Figure 6) He also 
advertised. However, Holmes soon "found by experience in 
introducing this protection, that advertising a 'Burglar 
Alarm,' does not attract the attention of that large class 
of property holders who would gladly avail themselves of any 
decidedly valuable method known to be such, of protecting 
their dwellings from the midnight murderer and assassin. It 
has also been learned that this attention cannot be gained 
by canvassers with the instrument in hand to exhibi t . "'^'^ 
Therefore in 1861, in an attempt to increase appeal and 
respectability of the system, Holmes published A Treatise 
Upon the Best Method of Protecting Property From Burglars , 
and Human Life From Midnight Assassins . ^^ (Appendix F) This 
pamphlet lists over seventy subscribers and recounts sever- 
al testimonials regarding the effectiveness of the system. 

Over the next several years Holmes worked to perfect 
his product, and he appears to have achieved acceptance; 
"the demand for burglar alarms in private residences in- 
creased very rapidly." A second compilation of testimoni- 
als titled. Your Attention is Respectful 1 y Requested to 
the Fol lowing Testimonials , (Appendix G) was published in 
1868. It contained 200 glowing testimonials and a list of 

26 







Figure 6: Portable model of Telegraph House Alarm. Reprinted from Edwin 
T. Holmes, A Wonderful Fifty Years (1917), 15. 



over 1000 subscribers. The client list reads like a verita- 
ble who's who of the day. (Appendix G, pages 182-190) The 
majority were from New York, Connecticut, and New Jersey 
with a few from Philadelphia and as far west as Detroit and 
Chicago. In addition to his office in New York at 201 Broad- 
way, Holmes had, in order to service these subscribers, 
opened offices in Chicago (114 Dearborn St), Troy, NY (205 
River Street), and Philadelphia, PA (no address given). 

The original Pope patent simply produced the ringing 
of a bell when any of the connected doors or windows were 



27 



opened. Holmes improved the system by placing an annuncia- 
tor, which indicated the point from which the signal origi- 
nated, in the circuit. The annunciator designated the room 
in which a window had been left open when the house was 
closed, or, in case of an alarm, would show in which room an 
opening had been made.'*^ A sketch from the 1868 catalog and 
extant remains of his systems give a clear indication of the 
annunciator's appearance. (Figure 7) This type of indicator 
was called a switch annunciator. It operated "for the 
purpose of locating the part of the house operated upon by 
the burglar... it is not automatic, [yet it] still serves an 
excellent purpose ... when the alarm sounds the master of the 
house can, by moving the different handles in succession, 
quickly determine which belongs to the endangered room by 
finding which one is moved to stop the ringing of the 
bell." These switch annunciators could come with a dif- 
ferent number of knobs -- each customized with appropriate 
room identifications. (Figure 8) 




Figure 7: Switch annunciator. Reprinted from Edwin Holmes, Your Atten- 
tion (New York, 1868) 52.

Only one bell was required for the entire house and 
it, along with the annunciator, was usually located in and 
controlled from the owner's bedroom. The bell apparatus was 
manufactured in the Boston shop of Charles Williams until 
1876 when "a Machine Shop was also put in operation uptown 
in New York for the exclusive manufacture of all of our 
[Holmes] electrical instruments and appliances." No re- 
mains of the bell used in a Holmes system has been discov- 
ered; however, Holmes's 1861 and 1868 pamphlets contain de- 
tailed sketches. (Figure 9) Switch "G" is the on/off control 
which attached the entire house at night and detached it in 
the day-time. A review of Holmes's city directory advertis- 
ing from 1867 to 1900 (Figure 10) suggests that at least 
outwardly the appearance of the bell used in the system did 
not change much from that depicted in the 1868 booklet. 

Because its noise is produced by a series of blows in 
rapid succession, this bell is given the name trembler. 
Although this bell will ring constantly while there is a 
completed circuit, it is not a continuous ringing bell and 
this is a drawback of consequence. In other words, if some- 
one opens a door, quickly enters, and closes the door again, 
the bell will ring briefly and stop. Only for the duration 
of the ringing could the annunciator be utilized to deter- 
mine the area of the house in which the disturbance oc- 
curred. In the previous scenario, for example, was it a 
servant or child opening a door without realizing the system

was activated -- or a burglar entering? By the time the 
house is searched the burglar, if he is the culprit, will 
have come and gone. 

Generally, basements, as well as first floors and 
second floors were alarmed. Every exposed door and window 
had to be connected with the annunciator/bell. Insulated 
wire was needed to maintain the integrity of the electrical 
circuit and to protect the conductors from damage. Reported- 
ly, "the only insulated wire to be had at this period was a 
very fine copper wire wound with silk, such as was used for 
the making of magnets in the various telegraph instruments" 
while what Holmes needed was a "large size insulated wire." 
Holmes's solution was to have "no. 18 bare copper wire 
braided with cotton" and coated with green paint. It was by 

this same process that Holmes was supplied with insulated 

5 2 
wire until 1870. Patrons are assured that, "not a wire, 

or spring, or machinery of any kind, but the bell, can be 

seen in the house." However, the method of installing the 

wire is never explained except to say, "it can be introduced 

into any house without defacing it in the least; not a board 

is removed, not a mark or scratch can be seen in conse- 

quence; it occasions no inconvenience whatever. 

Extant remains confirm use of 18 gauge copper wire 

wrapped, not braided with a green tinted thread. These wires 

were led from the main annunciator (Figure 11) iji grooves 

cut in the f i oor boards to the window or door opening 

33 




Figure 11: Wires exit from the point on the reverse of the main annunci- 
ator panel and begin their journey to encompass the perimeter of the 
house. ( Lockwood -Mathews ) 

(Figure 12) where they then go behind paneling or trim to 
reach the contact switch or key. These grooves are so true 
and regular (Figure 13) they appear to have been cut using a 
specially designed tool. To date, the only image of a 
floor groover is from the 1887 E.S. Greeley catalog. (Figure 
14) Grooves have only been found in plain wood floors, 
which, between 1850 and 1875 were usually fully carpeted in 
houses of the wealthy. ^'^ Therefore, one may assume that any 
floors with visible wiring today, were, at the time of alarm 
installation, carpeted. The manner of applying wires to 
rooms with decorative flooring (inlaid or stone) which was 
meant to be exposed has not been determined.

Contact switches, or "keys" were applied to all 
alarmed doors and windows. Because this is the place where 
the two circuit wires were brought into contact with each 
other to complete the circuit the proper action of the key 
was crucial to the successful operation of the system. 
Pope's original patent explains the form and function of the 
key in some detail. When applied to a door (Figure 15) the 
key consisted of a small fixed metal plate [L], attached to 
the door frame; and a metallic spring [M] secured to the 
door and housed in frame recess [N]. One of the wires [K] 
leading from the battery ends at metallic plate [L]. The 
second battery wire [P] is connected to the spring [M] . On 
the inner edge of the door, is a small stud or pin [O] 
projecting from the door. Because pin [O] projects against 



36 



the spring [M] it forces or presses the spring away from 
plate [L]. With the door closed the circuit was broken. 
Opening a door causes the metal spring [M] connected to the 
battery wire [P] to move against the plate [L] connected to 
the circuit wire [K] , which completes the circuit by con- 



necting the battery to the bell

As applied to the window (Figure 16) the key is de- 
scribed in the following manner: [E] and [F] are window 
sashes of window frame [G]. Wire [P/X] is led from the 
battery and extended into the window frame and connected 
with the lower end of metallic spring [b] . This spring [b] 
is located on the pulley stile of the frame and rests 
against the edge of the sash. The edge of the sash is shaped 
in a manner so that when the window is raised the spring [b] 
is pressed against the end of the second battery wire [Y] .

Three known circa 1868 installations, however, show 
that the key used on both doors and windows had changed in 
appearance since 1853. Holmes's window and door springs were 
made, until 1876, at a little shop in Chatham Square. ^^ 
Door and casement window contacts are a single self-con- 
tained unit applied to the frame. (Figure 17) These are 
called dotting contacts. (Figure 18) The key is inset into 




Figure 17: Visible portion of door contact (dotting). ( Armour -Stiner)

the frame until just plate [b] is flush with the wooden 
surface. When the sash or door is closed it pushes rod [r] 
in against the pressure of the spiral spring [s], which 
causes the arm [a] to break contact with plate [d] which is 
insulated from the framework. When the door or window is 
opened, even slightly, the rod is released and the circuit 
closed by arm [a] moving up and into contact with plate [d] 



40 



each of which are connected to circuit wires [t]. When fixed 
in the rebate of a closed door or window the points of 
contact are kept apart; but as soon as it is opened, the 
stud passes outward through the hole, and the points of 
contact come together and complete the circuit of the wires 

c n 

in connection with the bell. 

When extant systems on double hung windows were stud- 
ied, accessibility and visibility made it impossible to do a 
complete examination. In the best case scenario it was 
possible to examine a portion of the key let into the frame. 
For lack of an official name, these will be referred to as 
plate-type contacts. A small square plate of metal (1/2" by 
1/2") affixed by two screws (Figure 19) is attached to the 




Figure 19: Window plate-type contact. (Lockwood -Mathews) 



41 



window frame on the sash weight side. This is the contact 
point for one of the circuit wires. It is located at the 
point just below where the top rail of the bottom sash 
rests when in a fully closed position. It is only visible 
when the bottom sash is fully raised. This feat, because of 
design or age, is often not possible. (Figure 20) The second 




Figure 20: Window design does not permit window contacts to be seen. 
(Beechwood) . 



42 



circuit wire and contact point is 1 or 2 inches above the 
first. It is placed in such a manner that it is hidden by 
the top rail (of the bottom sash) when the window is closed 
and by the bottom rail when the window is open. Occasional- 
ly, when the sash has adequate play the wire leading to the 
second contact plate can be seen. Although it was not 
possible to remove a window sash to examine a complete key 
-- it is fairly evident how the system worked. One would 
expect to find some sort of a metal plate let into and 
running the length of the side of the sash corresponding to 
the circuit wires in the frame. This plate would begin on 
the sash just below the point corresponding to where the 
upper wire terminates. Therefore, when the window was fully 
closed the circuit was not complete. Raising the window, 
even slightly would cause the plate in the sash to bridge 
the gap and effectively connect the two circuit wires. 
(Figure 21) 

The power supply for the entire system was an electric 
or galvanic battery, protected from damage by an enclosure 
twenty inches long, nine inches high, and six inches wide 
secured by a lock and key. (Figure 22) The box was not 
offensive, and it could stand in any out of the way closet 
or pantry. Maintenance consisted of the addition of a few 
cents worth of vitriol in the battery six times a year. 
Because it was necessary to inspect the batteries from time 
to time, boxes were specially made -- with double hinged top

and sides, so that when the catch was released these fall 
flat allowing access to or removal of any individual cell. 
In fact. Holmes reports, "it is so simple and so easily 
taken care of that a child can do it." Although Holmes fails 
to name the specific battery type recommended for use in the 
system, by the 1860s certainly it was a two fluid wet cell 
battery. ^^ 

Holmes's publications make no mention of the cost of 
the system. Family names associated with wealth and social 
prominence predominate on the subscriber list. The grandeur 
of most of the case study homes supports the notion that in 
the early years, at least, only the most affluent could 
avail themselves of this technology. Patrons are told "it 
requires from four to sixteen days to apply one to a 
house. "^^ Several subscribers indicate that the piece of 
mind was well worth the financial outlay. However, only one 
testimonial suggests a price for the system: "It is the most 
satisfactory hundred dollars I have spent about my house." 
The writer does not indicate if this was a fully installed 
price and, the number of days required. 

This completes the review of the basic alarm package 
offered to subscribers. Subsequent changes to the system 
were either options, or improvements to a feature of the 
basic Holmes system. The basic alarm outfit available to 
subscribers consisted of an electromagnetic bell, a bat- 
tery, insulated copper wire, an annunciator, and a key (or 

45 



contact switch) for each window and door.^-^ Over the next 
few decades, in addition to the introduction of new fea- 
tures, each of these basic components were refined. 

The first positively dated improvement to the system 
came on March 26, 1867, when Holmes was issued patent number 
63,158 for an "Improvement in Electric Circuit-Breaking 
Clocks." (Appendix H) This mechanism could disconnect a 
circuit at any designated time of the day and leave it 
unconnected for a predetermined period of time. Additional- 
ly, it could reconnect at a predetermined hour. The attach- 
ment was introduced into the circuit attached to the doors 
and windows used by servants as they went about their 
early-morning chores. By breaking only this particular 
circuit the sounding of the alarm which would awaken the 
residents of the house was prevented. However, opening of 
any other door or window would, as usual, activate the 
alarm. ^2 (Figure 23) 

Several other improvements or options are described in 
the 1868 Holmes booklet. First, the ability to divide a 
house into two zones was introduced. "The alarm can be set 
for a part of the house, and not the whole, if desired. "^■^ 
Although no substantiating patent has been found, it is 
suspected that, at least initially, zones were established 
at the time of the system installation. For example, a 
household might be divided into upstairs and downstairs

zones. While a party was taking place on the first floor -- 
doors and windows in these public rooms would be in use by 
guests, and therefore, this zone would be turned off. The 
second floor however, would probably be empty -- with serv- 
ants and residents alike, all involved in the entertainment. 
Therefore the alarm might only be set for this unoccupied 
zone. The bell diagrams (Figure 9, page 31) shows three 
wires leading into the left side of the bell. This suggests 
a two-zone situation where one wire would be common and each 
of the remaining two would be in control of the zone se- 
lected or omitted. (Figure 23). 



47 



Second, Holmes claims, "windows can be left open 
sufficient for ventilation, and the alarm given if they are 
moved from their respective places." No patent associated 
with this improvement to the key portion of the apparatus 
has been identified. However, this feature was probably 
accomplished simply by making a break in the metal strip 
affixed to the sash. Originally, this piece would have run 
the entire length of the window sash, but by installing two 
strips of metal with a space between them -- the window 
could be opened to this point -- enough to provide air -- 
but not enough for a person to crawl through. Any subse- 
quent movement of the sash would activate the alarm. 

Holmes also reports the effectiveness of the system in 
unoccupied residences. "This alarm is particularly valuable 
during the temporary absence of the family, as the bell 
makes so much noise, that no burglar will risk himself in 
the house while it is ringing, or the wires can be extended 
and the bell placed in a neighbor's house. "^^ This practice 
of having a neighbor remotely monitor an unoccupied prem- 
ises, was at least upon one occasion, undertaken. 

Our readers will probably remember the tragedy at 
Bay Ridge, where two burglars - who turned out to be 
the abductors of the child Charlie Ross - lost their 
lives in attempting to rob an unoccupied dwelling. 
The alarm having been arranged so as to sound in the 
residence of a neighbor, he, with his coachman and 
gardener, surrounded the house and awaited their 
exit, utterly unsuspected by them.^^ 



48 



The next improvement in alarm technology was the 
introduction of an automatic annunciator, which instantly 
identified the location of a disturbance. Although on July 
20, 1858, William Whiting was issued patent number 20,970, 
for an "Improved Electro-Magnetic House-Alarm" (Appendix I) 
which includes an automatic annunciator, there is no evi- 
dence to show that he or anyone else marketed it at this 

67 
time. Practical automatic annunciators were developed in 

the 1870s, although it is uncertain who was responsible for 
introducing the first model . 

Trade catalog searches show that three general classi- 
fications of annunciators existed: switch, drop, and needle. 
(Figure 24) Variations on the manual switch annunciator 
previously described remained in production until at least 
1893, presumably because it was inexpensive. The automatic 
varieties worked principally by the movements of a needle 
over a dial or by the falling of a drop. In a needle 
annunciator the arrows lie horizontal when in normal posi- 
tion, and when activated, point to room(s) indicated above 
them. In the drop annunciator, cards drop down in front of 
apertures arranged in rows on the annunciator face, or the 
name of a room is uncovered by a piece falling away. Trade 
catalogs advertise that these annunciators could be used 
interchangeably either for a burglar alarm or for a maid 
call system. The difference would be window contacts rather 
than a push button.

Western Electric Manufacturing Co., in 1877 claimed 

"the substitution of the Automatic Annunciator for the 

switch.. (an improvement which we believe was first success- 
es 
fully and publicly introduced by oursel ves ) . "°° This needle 

style instrument was developed by Elisha Gray and patent 
118,231 for an "Improvement in Electro-Magnetic Annuncia- 
tors" (Appendix J) was issued on August 22, 1871. This 
patent was improved upon and reissued (Appendix K) before 
the annunciator assumed a final form. It could come with or 
without a circuit breaking clock attachment. (Figure 25) A 
small switch at one side completes or opens the circuit, and 
on the other side, a knob controls the connection with the 
bell. A row of studs at the base allows for any desired 
group of openings to be disconnected. Therefore each circuit 
also represented an independent zone. By manipulating the 
lower row of keys alarm coverage could be adapted to a 
variety of situations giving increased flexibility over the 
two zone system Holmes offered in 1868. Besides giving an 
alarm with a burglary attempt the annunciator can also show 
whether a building is properly secured. A forgotten window 
or door will be pointed out, an important feature in large 
business establishments with many openings. By disconnecting 
the bell, this test can be made silently. ^^ (Appendix L) 

Holmes's earliest confirmed availability of an auto- 
matic annunciator came on February 20, 1872, when Charles E.

Chinnock of New York assigned to Edwin Holmes patent 123,808 
for an "Improvement in Electro-Magnetic Annunciators." 
(Appendix M) This annunciator face resembles Holmes's 
earlier switch annunciator but rotating from the center is a 
needle which points to the room in which entry is made. A 
Philadelphia circular of the early to mid-1870s indicates 
that Holmes also offered a drop style annunciator. (Appendix 
N). On August 17, 1875, after the death of William Whiting, 
his 1858 patent 20,970 for Electro-Magnetic House-Alarms, 
which described a drop style annunciator was reissued and 
simultaneously his executors assigned it to Edwin T. Holmes, 
son of Edwin Holmes. (Appendix O) 

An improvement over the earlier trembler bell was a 
continuous ringing bell, where the ringing action, once 
started, continued either until the battery was exhausted, 
or until it was stopped by resetting the system. Holmes's 
November 7, 1871 patent 120,744, (Appendix P) for an "Im- 
provement in Circuit-Closers for Electrical Burglar-Alarms 
and Signals," produced a "continuous alarm" by activating an 
independent circuit into which the bell was placed. 

Up until this point, the most obvious indication of an 
alarm system is the presence of floor-embedded wires. Per- 
haps this method of wiring was unique to Holmes, but even 
so, at some point it became obsolete. Because of limited 
system remains from the 1870s and 1880s it is not possible 



53 



to say when wiring practices began to adapt to the current 
practice of concealing all electrical wiring in wall chases. 
As an intermediary step floor-embedded wires were replaced 
by wires fixed to the walls, "they may be concealed in the 
mouldings, cornices, or corners". "To keep the wires in 
position, bone insulators, may be used nailed into the 
wall," designed to meet various needs. Silk or cotton 
covered wires of which "all shades may be obtained to match 
the wall-papers and other furniture" were available. ^° The 
1889 Bel 1 Hangers ' Handbook reports "it looks better to 
"fish" the wires under the floors, above ceilings, and 
between the lathing of the walls."'^-'- 

A review of trade catalogs reveals that the window and 
door contact switches continued to evolve over the next 
decades. Door contacts (Figure 26) outwardly, at least, 
retained a very similar dotting contact profile, while 
window contacts (Figure 27) experienced more pronounced 
changes. Window contacts, as designed, up to this period 
were not without potential problems. The contacts were only 
found applied to the lower sash. A burgl ar-in- the-know 
could lower the upper sash and climb over, or, breaking the 
pane of glass could enter without raising the sash at all. 
Western Electric's 1877 catalog is the earliest example 
discovered to date where the first issue is addressed. While 
the catalog does not show an image of the contact, it does 
offer the option to connect only one sash of a window (two

dollars per window) or both sashes (three dollars per win- 
dow). Extant remains from Western Electric systems shows 
that their contacts were in the form of single or double 
compressible points. (Figure 28). 

Patent 120,875 (Appendix Q) issued November 14, 1871, 
to Edwin Holmes and Henry C. Roome for an "Improvement in 
Electro-Magnetic Burglar-Proof Curtains" addressed the 
second concern. The curtain, connected to the alarm appara- 
tus was suspended behind the window or in other suitable 
places and when moved or pierced, it would sound the alarm 
bell. In this case where there are no trade catalog promo- 
tions or extant remains, it is questionable if this alarm 
curtain was actually ever marketed, certainly, its success 
must have been less than spectacular.'''"^ 

Through the 1860s and into the early 1870s, Holmes was 
apparently the only provider of electric burglar alarm 
protection. The first evidence of competition with Holmes 
in the delivery of local burglar alarm protection is an 1872 
circular issued by George E. Cock and J.H. Guest of the 
Electro-Magnetic Fire and Burglar Alarm Telegraph office. 
(Appendix R) Mr. Guest, claims, "ten years of practical 
application and study, has brought to a perfect system the 
arrangement of an Electro-Magnetic Alarm, and we confidently 
offer it as free from the annoying defects of the older 
efforts." If one assumes the claim of ten years experience 
is truthful, that would indicate Guest had been involved in

the alarm industry since 1862. To date, no hint of competi- 
tors with Holmes has surfaced before 1868. Additionally, 
the description of the system in the 1872 circular bears a 
tremendous resemblance to the Holmes descriptions, so much 
so that it is difficult to imagine that it was developed 
independently. Therefore the most likely source of Guest's 
experience would have been as an employee of Holmes. J. H. 
Guest of Brooklyn receives his first patent no. 79, 973 
(Appendix S) for an "Improved Electro-Magnetic Burglar and 
Fire Alarm" on July 14, 1868. Guest and Cock had evidently, 

by 1871 formed a partnership and begin to market their 

7 6 
system in earnest. The earliest patent registered jointly 

to Cock and Guest is no. 118,199 for and "Electro-Magnetic 

Burglar Alarm" on August 22, 1871 (Appendix T) . 

Development of Central Station Alarms 
Although the overwhelming majority of alarm installa- 
tions were in private residences, a number of banks and 
businesses were listed in Holmes's 1861 and 1868 publica- 
tions as clients. "The Telegraph House Alarm can be connect- 
ed with any shop, office, store, or public building in New 
York, in such a manner, that the opening of any door, win- 
dow, office or desk-drawers of the premises will ring a bell 
so situated that it can be heard by the police in almost any 
part of his beat." In such commercial premises the bell 
rather than being placed in the sleeping quarters, was made 



59 



larger and was mounted on the outside of the protected 
premises. If the establishment was burglarized an alarm 
would be rung, and if the sound itself did not scare away 
the intruder, hopefully the alarm would be responded to by 
anyone who heard it. While an external bell might effec- 
tively frighten off a first time intruder, such criminals 
were apt to attack again. Because high risk business sub- 
scribers could not be assured the alarm bell would generate 
the desired response they needed a more effective system to 
protect their premises. A preferred tactic would be to 
capture the burglar, eliminating a threat and discouraging 
others tempted to try their hand. The solution for these 
business houses, banks, and jewelers who were generally 
empty at night lay in circuits that could be continuously 
supervised and responded to from a central point. ^^ Howev- 
er, it would be several years before this central station 
concept, which was developed for other applications was 
applied to burglar alarms. 

As it is commonly known, central station protection 
originated with the municipal fire alarm telegraph systems 
of the 1850s. The next protection related application of the 
central station began on October 5, 1871, when Edward A. 
Callahan organized in New York City a company named "The 
American District Telegraph Company" (ADT) to market public 
district messenger or dispatch service. Callahan devised a 
system based on the Channing-Farmer fire alarm. Special 

60 



signal boxes (Figure 29) installed in homes and business 
establishments enabled the subscriber to transmit a coded 
signal to a central station and thereby obtain specific 
services. By rotating a pointer, the subscriber could select 
the type of service needed, initially either messenger or 
police, others were added later. The signal received at the 
central station indicated which box the call came from, and 
the desired service could be dispatched. ADT divided Brook- 
lyn and later New York City into small districts each served 
by a central station whose location was arranged so that no 
call box within the network was more than four blocks in 
distance or more than three minutes running time from the 
district office. ^° The service was extended almost immedi- 
ately to other cities; Chicago, Philadelphia and Baltimore 
being among the earl iest . ^■'- Although all the companies were 
patterned after the New York organization, none of them were 
directly affiliated with it. 

As a method of alarm security, the district telegraph 
call box was little competition to Holmes, and while dis- 
trict messenger services spread. Holmes was not idle. The 
next major advance in alarm technology developed as a result 
of the needs of the commercial subscriber. On December 20, 
1870, Holmes, with Henry C. Roome was issued patent number 
110,362 for an "Improvement in Electro-Magnetic Envelopes 
for Safes and Vaults & c." (Appendix U) In this system the

interior of a jeweler's cabinet or safe was lined with an 
electric envelope connected to a battery and alarm appara- 
tus. Included in the alarm was a galvanometer, a device 
which detected changes in current levels of electric cir- 
cuits. The lining is made of two pliable sheets of metal 
imperfectly insulated from each other, (by a coating such as 
gum-shellac and paper) or the sheets of metal are connected 
with each other by a resistance coil of metallic ribbon 
arranged in convolutions on the face of the sheet. In either 
arrangement, when the sheets are connected to the battery a 
slight current of electricity will pass from one to the 
other. A change in resistance in the closed circuit regis- 
tered on the galvanometer monitoring it and if the movement 
was above or below established levels, the alarm would 
sound. Attempts to perforate the envelope or lining would, 



62 



because the current no longer has to pass through he resist- 
ance coil or the imperfect insulator membrane, establish a 
perfect electrical connection between the metal sheets. 
Increased electricity flow produces a corresponding movement 
in the needle of the galvanometer causing the alarm to 
sound. If the battery connection was severed the electricity 

flow ceased, also causing the alarm apparatus to give a 

8 3 
signal. In this arrangement, when attacked, the safe or 

vault might sustain substantial damage or injury before the 

lining is reached and the alarm given. Therefore Holmes next 

designed a wooden cabinet to cover or surround bank vaults. 

(Figure 30) By applying the electric lining to the cabinet 

the alarm would sound before the thief could reach and 

damage the safe. Patent 120,874 for an "Improvement in 

Electric Linings for Safes" (Appendix V) was issued November 

14, 1871. The company began to market the system in 1872 and 

it was an immediate success. "Our protection met an urgent

want and many Banks and nearly all the jewelers of Maiden 
Lane were ready to place their orders with us for our pro- 
tection and the Holmes Burglar Alarm Company became quite a 
factor in the business life of New York." (Appendix W) 
Holmes's son describes, an 

electric- 1 ined cabinet with panels so exposed, that 
you could puncture the metal with a pin or any kind 
of a tool, and when one panel was ruined we could 
put a new one in, and this we exhibited in a large 
vacant room, the cabinet at one end and our galva- 
nometer apparatus at the other end of the room with 
a copper wire running between. ... Such experiments 
and exhibitions rapidly brought business and before 
we were ready to take it. It was not as difficult 
to obtain orders as it had been fourteen years 
previous . 

"Of course it is to be understood that the galvanome- 
ter and alarm, as well as the battery, are to be placed at 

It R fi 
any required distance from the structure to be protected. 

Instead of connecting the vault sensors "with a bell on the 
outside of the building" Holmes decided "to run the wires 
into a central office" equipped twenty four hours a day with 
guards who upon receiving an alarm signal would be dis- 
patched to investigate. The first central station service 
for burglar alarms was established in 1872 by Holmes on the 
top floor of 194 Broadway, New York, and shortly thereafter 
the Holmes Company opened a central station in Boston at 342 
Washington Street. ^^ (Figure 31) Holmes was awarded a 
diploma for the safe and vault invention in 1872 and 

received additional recognition when he exhibited the safe 

8 8 
cabinet at the 1876 Centennial Exhibition in Philadelphia. 



64 



The exact date at which central station alarm protec- 
tion was added to the residential roster of alarm services 
is uncertain. By 1875 The Telegrapher reports the beginnings 
of residential applications utilizing the local alarm con- 
nected with a district call box. "The ordinary domestic 
burglar alarm, which is now so extensively used, is often 
connected with the American District system, so that if any 
attempt is made to enter the house thus protected, whether 
occupied or unoccupied, an alarm is instantly sounded and 

recorded at the district office by the ever vigilant senti- 
nel."89

CHAPTER 3 
CASE STUDIES 

In order to clarify patent and trade catalog descrip- 
tions, inspection of actual system remnants was essential. 
Examining a variety of houses with different versions of the 
Holmes system and of competing companies' systems would have 
been ideal. However, identifying a representative group of 
case studies was to prove impossible. Although Holmes's 
publications referenced more than 1200 customers, these 
listings are limited to installations done during the ten 
year period between 1858 and 1868. During the course of 
research, no comprehensive listing for the competitors was 
found. The case studies presented therefore, were selected 
not because they are the most appropriate remnants in exist- 
ence, but because they were identified at all. Some of the 
case studies are private homes, others museums or public 
buildings. All of the owners/ caretakers permitted, to 
varying degrees, investigation of the physical remains, and 
provided copies of archival materials when they existed. 

Three of the case studies are known to be Holmes sys- 
tems installed between 1861 and 1868: Lockwood-Mathews 
Mansion, Norwalk, Connecticut; the Bowne House, Flushing, 
New York; and the John Fraser House in Riverton, New Jersey. 

66 



Beechwood, in Newport, Rhode Island, while not positively 
identified, is almost certainly a Holmes system of this same 
period. The Armour-Stiner (Octagon) house, in I rvington-On- 
Hudson, New York, is post 1872, and was probably installed 
by one of Holmes's early competitors. Wilderstein in Rhine- 
beck, New York, and the Maish house in Des Moines, Iowa, are 
both Western Electric systems of the 1880s. 

In addition to the problem of selection there are 
other shortcomings. First, there were limits in terms of 
intrusive tactics. For example, removal of a window sash to 
determine the form and features of the key applied thereto, 
and dissection of a dotting key would have been desirable 
but was not realistic. Second, archival material about each 
house and its various development stages was often non- 
existent or spotty. Searching for site-specific documents 
might have been helpful in developing a broader understand- 
ing of the system but was not possible because of time 
constraints . 

In spite of these limitations, the case studies do 
reveal information about the system and in some instances 
raise important questions. In light of the fact that each of 
these houses is quite outstanding, the case studies begin 
with a review of the information regarding the house and its 
inhabitants. Following is a synopsis of the extant system 
remnants and their implications.

Lockwood-Ma thews Mansion Musei 



Norwalk, Connecticut 

The building known today as the Lockwood-Mathews Man- 
sion Museum was the largest private residence designed by 
architect Detlef Lienau (1818-1887) (Figure 32). Elm Park, 
as the estate was originally called, was constructed between 
1864 and 1868 for LeGrand Lockwood (1820-1872). The house, 
consisting of over fifty rooms, was described by one news- 
paper article as "the most magnificent country seat in 
America." When constructed, it was outfitted with many 
innovative building systems and features including numerous 
bathrooms, a central steam heating system, a 2000 gallon 
water tank in the attic as well as a theater, a bowling 
alley, and, of course, an electro-magnetic burglar alarm. 

LeGrand Lockwood was born in Norwalk, Connecticut, in 
1820, and moved to New York City in 1832. At the age of 18, 
Lockwood began his career as a clerk in a Wall Street bro- 
kerage firm. In 1843, he became a partner in the firm Genin 
and Lockwood (1843-1856). When Genin retired, in 1857, 
Lockwood was left as senior partner of the then Lockwood and 
Co., (1857-1873) Brokers at 22 William Street. The firm 
financed and managed several emerging railroads, sold 
stocks, and during the Civil War, government bonds. Lock- 
wood and Co. was noted for "its prominence and stability 
during the war, and its large subscription to national loans 
established its position as the leading stock house of the 



68 



country and thereafter its business assumed the additional 
character of a private banking firm. 

In 1863, Lockwood began purchasing land in Norwalk 
along West Avenue. ^"^ It was on this land that the mansion 
was constructed. The New York Times of August 5, 1867, said 
it would "cost, with grounds, nearly two millions of dol- 
lars, and when completed, will stand with scarcely a rival 
in the United States." In addition to the main house, the 
thirty-acre parcel had twelve outbuildings, including: a 
gate lodge, several greenhouses, a carriage house, and a 
stable. (Figure 33) The estate stood as an impressive 
monument to a new class of men who were responsible for 
America's transition into industrial greatness.

LeGrand had married Ann Louisa Benedict (1823-1882), 
also a Norwalk native, in 1842. The Lockwoods had six 
children who survived to adulthood; five boys and a girl. 
(Appendix X) The Lockwood family moved into the unfinished 
estate in 1868.

The attempts of Jay Gould and James Fisk to manipulate 
the gold market were to result in Black Friday, on September 
24, 1869. The precipitous drop in the price of gold bank- 
rupted Lockwood and Co., along with many other brokerage 
houses. As part of the effort to reestablish Lockwood and 
Co. and to satisfy his creditors, Lockwood mortgaged the 
uncompleted Elm Park on November 5, 1869. Although success- 
ful in reestablishing the firm, Lockwood's premature death, 
at the age of 52, on February 27, 1872, and the panic of 
1873 ultimately resulted in the failure of the firm. After 
his death, his widow sold his substantial art collection, 
and in 1873 the estate was put up for sale. Mrs. Lockwood, 
Henry and the three youngest children then moved back to New 
York City to live with LeGrand, Jr., and his family. In 
1874, when Mrs. Lockwood was unable to make the final mort- 
gage payment, the Lake Shore & Michigan Railroad foreclosed 
on the property, ending the Lockwood era. 

It is from the several sale announcements placed in 
papers of the day that much of the information regarding the 
original outfitting of the completed mansion can be ascer- 
tained. Of specific interest are the various comments 
regarding the security system. Statements ranged from the 
incorrect "there is a Burglar Alarm connecting with every 
door and window in the house,' to the more precise "there 
is an electric burglar alarm connected with all the exterior 
doors and windows on principal and second floors. It has 

71 



two indicators, one at the door of chamber "c" on the second 
floor, and one at the end of the hall on second floor of 
servants' quarters." (Figure 34) 

The house was sold to Charles Drelincourt Mathews 
(1821-1879), a prominent New York importer. Fortunately, 
"while Mathews occupied the mansion they made no structural 
changes in the building."'' The Mathews family occupied the 
house until 1938. In 1941, the City of Norwalk purchased 
the estate for park purposes. The mansion was then used as 
city offices and for storage space. In the early 1960s it 
narrowly escaped demolition and in 1969 was opened to the 
public as a museum. 

Although construction began on Elm Park in 1864, the 
family did not take up residence until 1868 and therefore 
the system is believed to date from the latter year. As 
LeGrand Lockwood is listed among the Holmes subscribers in 
the 1868 brochure, the system is certainly no later. 

The remnants at Lockwood-Mathews Mansion are the most 
intact of the case study group. This house has two 15 knob 
switch annunciators which each measure 5 1/2" in diameter. 
(See Figure 8, page 29, bottom) The first is located in the 
second floor hall between the master bedrooms and the second 
in the hallway of the servants' wing. Each knob appears to 
represent a group of contiguous rooms. (Appendix Y) 

The bel 1 /annunciator station at the master bedroom 
location was built into a cabinet which measures 5' 7" tall

by 18" wide. (Figure 35) In the servants' quarters the an- 
nunciator is applied directly to the wall, above a shelf and 
its supporting bracket. (Figure 36) The dimensions of this 
shelf matches a ghost image which appears on the main panel. 
The bell at the main panel is not original and there is no 
bell at the second location. The lone knob on the left 
side of the main control panel was almost certainly used to 
control zoning. (Figure 37) The system is attached to first 
and second floor windows and exterior doors. Plate-type 
contacts are applied to the double hung windows and dotting 
type keys are found on the casement windows and doors. (See 
Figure 34, Page 73) Because there are bars on the basement 
windows these, as might be expected, are not alarmed. Room 
indicators on the annunciators tell us (although no evidence 
remains) that the wine cellar and the exterior cellar doors 
were alarmed. 

The first names on the annunciator are Florence, 
Arthur and Willie, all Lockwood children. The appearance 
of these names raise questions regarding previously as- 
signed room use. Although the third floor is not restored, 
interpreted or open to the public, it is believed that these 
rooms were "bedrooms for the younger children and their 
governess . "•'"'^'^ While the second floor suites "were used by 
the older Lockwood sons and by guests . "•^°-'- If this were the 
case, since the third floor is unalarmed, one would not 



74

expect to find the names Florence or Arthur on the annuncia- 
tor. This, therefore suggests, that these children must 
have had designated rooms on the second floor. 

Additionally, because the names on the annunciator 
remain to this day it is concluded that during the Mathews 
family occupancy (whose children were named Lillian, Harry, 
Florence and Charles) the system was either not used or it 



75 



was no longer functioning. This assumption is made for two 
reasons. The Mathews family certainly could have, and 
probably would have changed the annunciator knobs to reflect 
the uses and names of their period. The continued existence 
of the Lockwood children names, indicates this was never 
done. Secondly, in a written reminisce by Florence Mathews 

she writes about the second summer in the house (1878), and 

10 7 
reports a successful robbery. If the alarm system had 

malfunctioned or contrary to general practice, was not on at 

the time, one would expect Florence to mention that fact, 

which she does not.

Annunciator knobs suygest a second, minor inconsisten- 
cy in room usage theory. On the first floor, opposite the 
main stair to the basement is a small room, now the Educa- 
tion Curator's office, called 'estate office or breakfast 
room'. No such title appears on the annunciator. What does 
appear is "Billiard and Lunch Room." The billiards rooms 
are in fact a neighbor, therefore it is proposed that this 
room's original function was as a lunch room. 

Except where there are highly decorative floors or 
where wall-to wall carpeting is currently installed - floor 
embedded wires are apparent throughout the building. At two 
locations in the house Roman numerals are carved in floor- 



77 



boards. (Figure 38) First, below a window in Mr. Lock- 
wood's bedroom the numerals I, II, III and IV are carved in 
the floor. At this point each of the three wires disappears 
into a hole in the floor. Presumably, they go down to 
service the first floor and basement. The second marking, 
IX is in the room which today is referred to as the Moorish 
room. These types of markings were not found at any of the 
other sites and their significance is unknown. 

Bowne House 
Flushing, New York 

Bowne house is one of the few remaining examples of a 
vernacular building type combining a mixture of Dutch and 
English characteristics, common in Long Island at an early 
date. The original eastern wing, built around 1661 and 
enlarged circa 1669, joins the larger western wing, (built 
1680, added to 1695 and altered around 1830) by an irregular 
sloped two and one-half foot wide roof. (Figure 39) Former- 
ly part of a 200 acre farm, Bowne House located in Flushing, 
in what is now the borough of Queens stands on a lot less 
than one-half acre in size. The house survived massive 
urbanization in the late 19th and early 20th centuries, when 
little else did, and today is one of the few relatively open 
spaces in a area dominated by multi-story apartment blocks. 
John Bowne (16277-1695), an early settler on Long Island, 
was an important, although today, little known figure in the 
early history of America. After his death the house passed

through several generations of the Bowne family and into the 
Parson's name, until it was sold to the Bowne House Histor- 
ical Society on May 2, 1946.^°-^ 

Holmes's 1868 booklet lists Samuel B. Parsons, Flush- 
ing, LI, as a subscriber therefore it is fairly certain he 
was responsible for the installation of the system. 
However, during the 1860s there was shared ownership of the 
property and the identities of other family members/owners 
who may have resided at the house and for which years is 
uncertain. 

Window and door contacts outwardly appear to be iden- 
tical to those at previous case studies. The evidence of 
floor wires at Bowne House however, differs. In spite of the 
absence of decorative flooring, wires only appear in a 
limited number of rooms. "^^^ (Figure 40) This suggests that 
floorboards and windows have been replaced since the system 
was installed. Or, perhaps, this location illustrates a 
system applied to only portions of a house. This practice 
is suggested by Holmes when he states, "it is particularly 
valuable to connect with the doors of private rooms, bed- 
rooms, drawers in your furniture, closets where silver ware, 
jewelry and other valuables are kept, because when the door 

is shut and the alarm set, visitors, servants, relatives or 

•ilO 7 
domestics cannot open them without giving the alarm. 

Because of the shared ownership of Bowne House at this time, 

the configuration of the wires suggest that there might have 

80 




Figure 39: Bowne House, exterior 



been two independent households in residence and perhaps, 
the way in which they divided the house. Although no Bownes 
or Parsons appear in the 1861 Holmes list, xt is suspected 
that this house represents a fairly early installation, 

possibly between 1861 and 1853. First, floor grooves are not 

10 8 
nearly as regular (Figure 41) as at the other sites. 

Second, rather than concealed wires traveling between 

flours, at the Bowne House a set of exposed tracks is carved 

intL wall. These two pieces of evidence -- although not 

conclusive -- suggest lower level skills on the part of the 

installer. This may be understandable for a house in the 

hinterlands, away from the most competent and experienced

technicians. However, Bowne house is in fact the case study 
closest to Holmes's home office, and therefore, it is sug- 
gested that the quality of the workmanship is as a result of 
reduced collective {or corporate) skills and techniques, 
rather than a single installer's lack of competency. 

John Fraser House 
Riverton, New Jersey 

The small rural conmnnunity of Riverton, New Jersey, was 

founded in 1851 by ten men who engaged architect Samuel 

Sloan to design a village of summer houses. This community 

was the first wholly planned residential sub-division in 

America. Its proximity to Philadelphia -- only thirty 



83 



minutes by train and forty-five minutes by steamboat -- made 
possible commuting to Philadelphia and points beyond. 

An Italianate villa (Figure 42) was constructed for 
James Clothier, a founder of Strawbridge and Clothier, but 
was actually occupied by his brother, Caleb. The house, one 
lot away from the yacht club and the Delaware River was 
built in 1853 and is also believed to have been designed by 
Samuel Sloan. Evidence suggests that by 1860 the house was 
rented to the architect John Fraser, and subsequently (1866) 
it was purchased by him. At that time, Fraser was reported 



to have made extensive improvements to the property 



109 




Figure 42: John Fraser House, exterior. 



84 



John Eraser's architectural career spanned some fifty 
years, from the mid-nineteenth century to the turn of the 
twentieth. Fraser began practicing in Philadelphia in the 
early 1850s. He was, for a short time, in partnership with 
Andrew Palles and was a founding member, in 1861, of the 
Pennsylvania Institute of Architects, an organization which 
fell apart because of the Civil War. 

Following the Civil War, Fraser was joined, first by 
George Hewitt and later Frank Furness, to form, in 1868, the 
firm of Fraser, Furness and Hewitt. The firm only lasted 
until 1871. At the beginning of the 1870s Fraser maintained 
offices in both Washington and in Philadelphia. In 1873, he 
apparently was working exclusively out of Washington, D.C., 
and continued to do so throughout the 1880s until he re- 
turned to Philadelphia in 1890 to practice as John Fraser 
and Son. 

Although Fraser's work was centered in Washington, his 
personal life continued to be centered around his Riverton 
house. After the death of his only son in 1895, Fraser grew 
despondent and his health deteriorated. In 1897 the Fraser 
property was sold at a sheriff's sale to F.H. Hallowell, 
although the Fraser family (he, his wife and an only remain- 
ing daughter) continued to reside there as tenants until 
around 1903 when they moved to Philadelphia. Fraser died 
there in 1905. 



85 



In 1907 the house was sold to Maclean Jones who made 
extensive repairs and improvements. The house was broken up 
into apartments in 1925. Currently the owner, Louise Love, 
resides on the first floor and the second and third floors 
are divided into two apartments each. 

In the section of Holmes's 1868 brochure dedicated to 

"Philadelphia Names" is found this testimonial from John 

Fraser : 

430 Walnut St., Philadelphia, April 27th, 1868 

Mr. E. Holmes, Esq., -Dear Sir: - I consider 
your Burglar Alarm Telegraph a very important pro- 
tection to my house. 

The time required to take care of it I think 
would not exceed one hour in the course of a year. 

It was neatly, carefully, and without damage or 
inconvenience, applied to my house at Riverton, 
N.J., and is applicable to all first-class houses. 

It has given me entire satisfaction, and is the 
best Burglar Alarm that I know of. 
Yours Respectfully, 

John Fraser, Architect 

It is suspected that the alarm was installed in 1866, 
after Fraser actually purchased the house. Certainly, the 
installation was prior to April 1868, the date of Eraser's 
testimonial letter. Although it is certain that this house 
had had an alarm applied to it, the current owner did not 
recall ever seeing any of the component hardware. After 
subsequent correspondence and conversation she became in- 
trigued with the project and invited the author to visit. As 
it turns out, the system remnants at the John Fraser House 
are so totally obscured (more so than at any of the other 



86 



case studies) that unless a specific search is diligently 
conducted, evidence of the system would be easy to overlook. 

Through the years, this house has undergone extensive 
remodeling and repairs. On those windows and doors which 
are original multiple paint layers very nearly succeed at 
obscuring evidence of the contact switches. Close examina- 
tion did reveal that most of the first floor doors, and 
several windows on the first and second floors did still 
carry their hardware -- plate-type contacts on the window 
frames and dotting switches in the door frame. The third 
floor, as expected, revealed no evidence of a system. 

Generally, the most obvious indication of a system is 
the floor embedded wires. At the Fraser house virtually 
every floor surface is covered with tile, wall-to-wall 
carpeting or linoleum. One second floor room has just a 
large area rug and still, in the visible flooring - no 
evidence . 

In the living room, bench type seating is built into 
the bay window alcoves. The seats lift up and underneath is 
storage space. Here, finally were found the two tell-tale 
wires leading to the window. (Figure 43) If floor covers 
were removed it is suspected that examination of wiring 
patterns would suggest original room configuration. The lack 
of visible installation evidence shows just how easy it is 
to obscure system remnants.

Beechwood 
Newport, Rhode Island 

The bustling port City of Newport, Rhode Island, had 
its economy devastated during the Revolution, only to re- 
bound just prior to the Civil War when it became a popular 
summer resort. The forces of urbanization and industrializa- 
tion which introduced a rising class of industrialists 
elsewhere in the first half of the nineteenth century large- 
ly passed by Newport. The elite of Newport society were 
still playing the role of the eighteenth-century gentry 
whose wealth was based on commerce and local activities and 
not on new industry. 



88 



The new wealth which did come to Newport, beginning in 
the second quarter of the nineteenth century, was attracted 
by pleasant climate and superb beaches. Investments were 
made in resort-related activities rather than in manufactur- 
ing. After 1845, Newport was increasingly involved in specu- 
lation and building associated with the rise of its resort 
business, catering to wealthy vacationers from New York, 
Boston and the South. 

In 1851, the local speculators Smith and Baily, pur- 
chased 140 acres of land which would become Bellevue Avenue, 
Newport's street of millionaires. In 1852 Daniel Parish ( ? 
- 1879) was among the first twelve persons to purchase a lot 
and to erect an expansive and impressive summer cottage. 

Daniel Parish was a New York merchant. Between 1852 
and 1853 Parish engaged Andrew Jackson Downing and Calvert 
Vaux to design a house for him on Bellevue Avenue overlook- 
ing the ocean. This house, pictured in Villas and Cottages 
was totally destroyed by fire in 1855. Vaux subsequently 
rebuilt the house, duplicating the original plans, however, 
locating it closer to the sea and away from Bellevue Avenue 
on the site. (Figure 44) This home was just a summer resi- 
dence for Parish. ^-'■^ 

After Parish's death in 1879, the house was purchased 
by William Bachouse Astor, Jr. for $190,991.50. Between 
1888 and 1890 the house was substantially remodeled and 
redecorated by his wife Caroline. When Mrs. Astor died in 



89 




Figure 44. Beechwood, exterior. 

1908 the house was inherited by John Jacob Astor IV and 
remained in the Astor family until 1937. It has subsequently 
changed hands several times, before becoming the home of the 
Beechwood Theater Company. While currently open to the 
public for tours it is not operating as a museum. The resi- 
dent theater group recreates the Astor's life style of the 
1890s. They incorrectly interpret what remains of their 
alarm system as a maid call device. 

In the Beechwood installation, the floor wires follow 
patterns similar to those at the previous sites. The switch 
annunciator is not in its original location, it has been 
mounted on a board which is hung like a picture in the 



90 



second floor hallway. (Figure 8, page 29, top) This twelve 
knob version measures 4 3/4" in diameter and still has eight 
of the room indicator knobs in place. These read as fol- 
lows: Parlor and Dining room; Laundry; Basement Doors; 
Library and Recreation Room; Our Room; Mr. P. Jr's Room; 
Nursery; and NE Spare Room. 

Dotting type contact switches were present on casement 
windows but because of design (See Figure 20, page 42) it 
was not possible to examine the switch on the double hung 
windows. Although Daniel Parish does not appear on the 
subscriber list, because these features match so precisely 
the known Holmes installations it is almost certainly a 
Holmes installation. The system was probably installed 
after the Your Attention booklet was published in 1868 and 
before Holmes introduced his drop annunciator in the 1870s. 
An inventory prepared at the death Daniel Parish, shows a 
third floor room as the "burglars alarm storeroom." However, 
nothing listed in the room contents is related to the alarm. 
Because this floor is currently used for actors' housing it 
was not available for examination. If this third floor area 
is alarmed it would be unique among the case study houses. 

Armour-Stiner (Octagon) House 
Irvington-On-Hudson , New York 

The five-story, twenty-five room Armour-Stiner (Octa- 
gon) House is perched on a hill overlooking the Hudson River 



91 



in the Town of I rvington-On-Hudson, New York. This area and 
the surrounding hills were, beginning in the mid-nineteenth 
century, a popular summer retreat. Situated on the east 
bank of the Hudson River, the location is just twenty miles 
north of New York City, an hour away by train. 

Here, in 1853, Paul J. Armour {18307-1886) purchased 
four plots of land on West Clinton Avenue. Armour was a 
banker and broker with offices in lower Manhattan. Between 
1858 and 1860 he constructed a two-story octagon house. 
Octagon houses had become a popular form of construction 
following the publication of Orson Squire Fowler's The 
Octagon House , A Home for Al 1 (1848). Fowler claimed that 
eight-sided houses, in addition to being more efficient and 
economical, were healthier. Armour's house, a modest two- 
story structure was originally built five feet above ground 
level and therefore, the basement was made a fully function- 
al space through numerous windows which provided light and 
ventilation. The main entrance faced Clinton Avenue. 

Armour died in 1866, but his family remained in the 
house until 1872, when the house was sold to Joseph H. 
Stiner (1827-1897). Stiner, a prominent New York City tea 
and spice merchant, purchased the house as a weekend re- 
treat. He immediately undertook extensive renovations and 
expansion of the house. The present-day structure was 
created by adding the dome with cupola and verandah as well 
as reorienting the entrance to the house. (Figure 45) 

92 




Figure 45: Armour Stiner, exterior. 

These alterations were so extensive that the entire struc- 
ture was effectively rebuilt and therefore the house is 
considered an 1872 construction. Although hundreds of 
octagon houses were built, the Armour-Stiner House was quite 
distinctive and is thought to be the only fully domed octag- 
onal residence in the world. 



93 



In 1881 Stiner suffered a series of financial reverses 
which led, in 1882, to the sale of the house to George W. 
Dibble (1848-1917). The house once again became a year- 
round residence. There were several additional owners 
before the house was purchased, in 1979, by its current 
owner, Joseph Pell Lombardi . Lombardi , a preservation 
architect has spent much of the ensuing time researching and 
restoring the house to its 1872 appearance. 

While the exact date of this alarm installation is 
unknown it is expected that the system was added as a part 
of Stiner's major remodeling in 1872. Windows and doors 
which were first introduced during this remodeling are 
alarmed so the installation certainly is no earlier than 
1872. Floor-embedded wires identical to those previously 
seen are found throughout much of the first floor. Accord- 
ing to the owner, wires were only present at one spot on 
the second floor. This area was the sitting room of the 
master suite, and therefore, the expected location of the 
annunciator -- which is no longer present. Because of the 
raised basement configuration, this second floor is effec- 
tively equivalent to the third floor at the other houses and 
therefore would not be expected to be alarmed. Examination 
of windows for confirmation was not, however possible. 

Dotting contact switches, in addition to being found 
on the exterior doors, and casement windows in the basement 
were also found on several interior doors in the basement. 

94 



The original room usage -- as a wine cellar and as the 
mechanical or furnace room helps in understanding the place- 
ment of these contacts. (Figure 46) Alarming the door to the 
wine cellar allowed for monitoring access of the servants. 
The mechanical room with its coal shoot might have permitted 
entry to the building. By alarming the interior door an 
intruder could proceed no further without detection. These 
door switches, although identical in appearance to those in 
the previously discussed case studies, differed slightly in 
their application. Where previously the contacts are locat- 
ed approximately six inches above the floor, at Armour 
Stiner all the basement contacts are found about six inches 
from the top of the door. Presumably the wires were snaked 
through the wall to this contact point from above. Certain- 
ly, it would have been easier to locate the contact at the 
top of the door frame rather than the bottom. 

The most perceptible difference at this installation 
is the window contact switch. Although located in the same 
position as the plate type contacts, here, the appearance 
differs. A piece of springy metal approximately 1/2 inch 
wide by 2 1/2 inches long is affixed at its lower end by two 
screws. (Figure 47) The thread wrapped wire can be seen 
leading to these screws. No patent has been found for this 
type of contact. However, this form of the contact switch 
appears to be similar, if not identical, to that described 
in the 1853 Pope patent. (Figure 16, page 38) Although this

installation is undoubtedly post-1872 the technology of the 
window contact bears more of a resemblance to the earliest 
contact forms than to the latter versions. For this reason, 
it is suspected that this particular system was installed by 
a competitor of Holmes who might still have been using an 
older form of the technology.

Maish House 
Des Moines, Iowa 

In 1870 George H. Maish (1835-?), recognizing "condi- 
tions and opportunities in different parts of the country" 
moved from Pennsylvania (where he was born), to Des Moines, 
Iowa. He was determined "to try his future in the west, 
where he believed superior advantages were offered." At 
first, he was engaged in the drug business with his 
brother-in-law Charles A. Weaver, and in 1875 he was among 
the group of men who organized the Iowa National Bank of Des 
Moines and was elected to the position of Cashier. He went 
on to become prominent in the financial and business circles 
of the city.^^^ 

In 1882 Maish completed the construction of a new 
house for his family. The two story house with a cellar is 
believed, to be the first house in the area with a burglar 
alarm. Georgia Elizabeth Maish, daughter of George recount- 
ed, "how she was awakened one night by the bell, jumped out 
of bed and ran to the window. From the window she saw a man 
running thru the backyard away from the house. The family 
were very pleased to know the alarm really worked ."■'■■'■ '^ 

The house, at 1623 Center is currently owned by Ralph 
Gross and has the remains of a Western Electric alarm sys- 
tem. It is suspected that this system was installed at the 
time the house was constructed, in 1882. The 9-needle annun- 
ciator with bell (See figure 25, page 52, left) is virtu- 



98 



ally identical to the annunciator depicted first in the 1877 
Western Electric catalog and again in their 1883 catalog. 
Room titles (or zones) appearing on the annunciator are: 
Parlor and Sitting Room; Library; Dining Room and Kitchen; 
Inside Door; South East Chambers; West Chamber; Bed and Baby 
Room; Northwest Chamber, and Back Door. The system is 
connected to all the windows and doors including the inter- 
nal doors. Contact switches in the doors are brass dotting 
contacts 3 1/4" high by approximately 3/4" wide. The 
window contacts are double sash compressible triangles. (See 
figure 28, page 58) 

Unlike all of the previous case studies, the connect- 
ing wires are not floor-embedded; they travel instead to the 
attic and then descend to the various levels of the house. 
The wire is 18 gage wrapped in thread and color coded, one 
white (the common), one black, with positive leads connected 
in the attic to one white wire leading to the annunciator. 
In order to accommodate passage between floors holes 3/8" 
wide are bored through the flooring for each wire which are 
then stapled along interior studs. There are nine circuits 
throughout the house, delineated primarily by room.-'--^^ 

Two of the circuits have been recently repaired. The 
others have been tested, and in the majority there are 
shorts. The most common shorts are in the switches at the 
windows. The springs that hold the contacts out (open) are 
broken and thus short those circuits.

Wilderstein 
Rhinebeck, New York 

In 1846, Thomas Holy Suckley received a substantial 
inheritance from his father George Suckley, who made a 
fortune investing in Manhattan and New Jersey real estate. 
Joining the rich and fashionable in their up-river migra- 
tion, Thomas Suckley, in 1852, built a house on a 35 acre 
site set high on a bluff overlooking the Hudson River in 
Rhinebeck, New York. The house, known as Wilderstein, was 
designed by architect John Warren Ritch. This modest Ital- 
ianate villa was "two stories high and had a low Tuscan roof 
resting on moulded right-angle brackets.' 

Upon Thomas's death in 1888, Robert Bowne Suckley, 
his second, and only surviving son, took possession of 
Wilderstein. Within a year he had transformed it into the 
Queen Anne mansion seen today. "The roof was taken off and 
the walls raised with an overhanging third story and gabled 
attic. An entrance porte cochere, a tower, and a service 
wing were added, and the verandahs extended and profusely 
decorated. "■'■■'■'' (Figure 48) 

Robert and his wife, Elizabeth Philips Montgomery had 
seven children. Their eldest daughter, Margaret Lynch Suck- 
ley (born 1891) resides at Wilderstein. In 1983 a non-profit 
organization, Wilderstein Preservation, dedicated to saving 
the house was incorporated. Miss Suckley gave the house and 
property to the organization while retaining a life tenancy.

Family records indicate that in December 1888 Robert 
Suckley himself directed the installation of the heating, 

burglar alarm and bell systems for the main house making 

118 
this the latest (or youngest) of the case studies. The 

alarm system chosen was Western Electric and like the Maish 
house, wiring was not exposed; door contacts appear un- 
changed. Both double and single sash window contacts are 



101 



present, although only the single was available to the 
author for examination. The exposed surface indicates it 
was patented December 23, 1884. There is no patent number 
or patentee name so the exact patent has not been identi- 
fied. However, it bears a resemblance to a contact manufac- 
tured by E.S. Greeley in 1890. (See Figure 27, page 56) 

Wilderstein has two annunciators, similar, although 
not identical in appearance to each other. One was for the 
burglar alarm and the second for the maid call. The maid 
call device remains mounted in the present day pantry and 
bears the names of each first floor room. The burglar alarm 
annunciator was at some past time disconnected and is cur- 
rently stored in the attic. It is an 8-needle variety with 
clock attachment. (See figure 25, page 52) There is a sepa- 
rate, wall-mounted bell in the second floor landing which 
was presumably attached to the alarm system. Annunciator 
titles read: Kail, Dining Room, Library, Drawing Room, 
Kitchen, Laundry and Cellar -- indicating that the cellar 
was alarmed while the second floor was not. Although still 
battery powered, this Western Electric system was evidently 
supplied by Leclanche Batteries. 

Efficacy 
At its inception alarm technology, like any other, had 
room for substantial improvement -- there were numerous 
flaws to be corrected before a mature and reliable product 



102 



evolved. In 1881, when reporting about electric burglar 
alarms. Popular Science Monthly , summarizes the industry's 
development up to that point. "In its earliest forms there 
were many defects, but in a development of twenty years 
these have been mostly corrected. It has now attained a 
simplicity of construction and certainly of action that make 

it one of the more useful and trustworthy of man's servi- 

ti 1 20 
tors. Through patent analysis, examination of extant 

remains and trade catalogs this paper has sought to enumer- 
ate the technological progression which this building system 
underwent during its formative years. 

Patent analysis reveals what was developed, when, and 
how it worked; it does not however, show if an "item" ever 
went beyond research and development and into commercial 
production. By using these seven case studies and trade 
catalogs from the 1860s through the 1880s, the development 
chain was expanded beyond what patents alone can reveal. The 
resulting hardware chronology, although not comprehensive, 
revealed that some alarm system components stayed the same 
while others evolved dramatically. 

Understanding how early electric burglar alarms worked 
and how the hardware developed can, in conjunction with 
archival documentation, be used as a tool to either answer 
or suggest interpretive questions. This tool seems particu- 
larly well suited to understanding space utilization and 
changes over time. The degree to which this happens appears 

103 



to have a direct correlation to the extent of the archival 
documentation available. 

Unfortunately, despite all of the historic materials 
uncovered, the true effectiveness of these early alarms 
(those of the first generation; 1850s, 60s and 70s) has yet 
to be adequately documented. How well or effectively the 
earliest systems worked or how quickly they were integrated 
into daily life, is still unknown but it is an important 
part of the story, deserving additional research. 

The Holmes pamphlets list over two hundred testimoni- 
als. Only a small fraction of these specifically mention 
actual alarm incidents. Many of these letters were solicit- 
ed, those published were probably hand chosen and edited. 
The accuracy and representative nature of these incidents 
can not be assured. 

Anecdotal episodes reported in other sources might go 
a long way towards explaining at what point the systems 
became consistently reliable and effective. Unfortunately, 
to date, besides those appearing in the Holmes testimonials, 
very few references to activated alarms have surfaced. Two, 
however, should be mentioned. P.T. Barnum had a Holmes 
system in his Bridgeport, Connecticut home."'"^-'- In his auto- 
biography. Struggles and Triumphs he briefly mentions an 
instance when his alarm went off and he was able successful- 
ly to scare off the intruders. 



104 



My house was provided with a magnetic burglar alarm 
and one night the faithful bell sounded. I was 
instantly on my feet and summoning my servants, one 
ran and rung the large bell on the lawn which served 
in the day time to call my coachman from the stable, 
another turned on the gas, while I fired a gun out 
of the window and I then went to the top of the 
house and set off several rockets. The whole region 
round about was instantly aroused; dogs barked, 
neighbors half-dressed but armed, flocked over to my 
grounds, every time a rocket went up, and I was by 
no means sparing of my supply; the whole place was 
as light as day, and in the general glare and confu- 
sion we caught sight of the two retreating burglars, 
one running one way, the other another way, and both 
as fast as their legs could carry them; nor do I 
believe that the panic-stricken would be plunderers 
stopped running till they reached New York. 



Unfortunately, the successful sounding of the alarm is only 
used in this story to set the stage for P.T. Barnums' re- 
counting a somewhat unrealistic fireworks extravaganza. 

The experiences recounted by Mark Twain in his short 
story "The McWilliamses and the Burglar Alarm" (Appendix Z) 
were not nearly as complementary. A Readers Guide to the 
Short Stories of Mark Twain , claims that all three stories 
written about the McWilliams family between 1875 and 1882, 
were actually a reflection of Twain's own domestic life. 
This particular story greatly embellishes the difficulties 
of a mechanical system which never seems to work right. 
Because this story takes a frustrating situation and turns 
it into comedy, suggests that is has a basis in fact, to 
which the reading public could relate.

CHAPTER 4 
CONCLUSION 

Preservationists have been slow to acknowledge "secu- 
rity" as a building system worthy of their attention. 
However, it should be recognized that to the degree permit- 
ted first, by technology and second, by an owner's financial 
means, builders have provided for protection of possessions 
and persons throughout history. Since the colonial era 
these domestic security measures have taken a variety of 
forms. Included are architectural means: doors and shut- 
ters; mechanical means: locks and bells; landscape tech- 
niques: including fences and planting patterns and finally, 
electrical devices . While this examination of electric 
burglar alarms represents only a small portion of the com- 
plete chronology, the scholarly evaluation of building 
systems from any period should consider security provisions. 

Patent review and case studies have been used in the 
preceding analysis to provide an understanding of how alarm 
devices worked and evolved. This detailed knowledge is 
essential to the process of interpreting or preserving a 
surviving system. Edwin Holmes refined and improved the 
methods both for detecting and reporting burglaries. Al- 
though the technology has improved substantially, the range 

106 



of burglar alarm services which he developed are still in 
use today. 

However, without a basic understanding of the larger 
social context or cultural environment in which these de- 
vices were used, it is easy to ignore or misunderstand 
system remnants. The last half of the nineteenth century was 
thought of by many as a crime free, idyllic time. Where 
hardware is present, the tendency has been to mistake it as 
belonging to a different system or to a later period. 

This examination of the Holmes electro-magnetic bur- 
glar alarm telegraph has provided evidence clearly indicat- 
ing that electric burglar alarm technology was more wide 
spread and existed at an earlier date than is generally 
expected. In fact, the introduction of this type of system 
into the home is an example of an early, if not the earli- 
est, use of electricity in a domestic application. This 
technology predates, by almost thirty years the advent of 
electrical lighting.

'T<y(iH n-hoiii it viay cnuccrn: 

Beit kiuiwii Hint I, Augustus U. I'oi'i'-, of 
Somervillc. in tlio county of Middlesex and 
State of Miissaelmsctts, have invented a new 
and useful oriniptovcd Map;netic Alarm, to be 
applied to either a door era window, or both, of 
a (Iwellinfr-liousc orother buildinjr,f'ortlicpur- 
pose of f^ivinj;- an alarm in case of burglarious 
or other attempts to enter the same throu^li 
said door or window by opening said door (U' 
window ; and I do hereby declare I hat the same 
is fully described and repiesenteil in the follow- 
inj:; si>cci(ioatiou and the accompanying draw- 
ings, letters, lignres, and references thereof. 

Of the said drawings, Figure 1 repi(!senls 
an elevation of a door and window and my 
ai)i)aratus as a|iplied thereto. Fig. '2 is a ver- 
tical and transverse sectioii-t-ahi^n through ihe 
spring circuit-breaker to lie hereinafter de- 
scribed. Fig. o is a vertical section of the ap- 
paratus hereinafter termed Lhe " key" as ap- 
plied to the door. Fig. 4 is a section of the. 
same as applied to the window. 

In the said drawings, A represents a door, 
of wliich 15 is the frame, thesamc being shown 
as fitted into the wall. ]) Vj and V are win- 
dow-sashos of a window-frame, (1. 

n is an electro • magnet, fastened to llic 
side of Ihe wall in a convenient posilicm, and 
having a beli, I, arranged over or near to it. 
One of the pole-wires leading from an electric 
battery is seen at K. It extends to and winds 
around the magnet and passes upward over 
the bell and window-frame, and thence down- 
\TP.rd into thedoor-frame, where itisconnec^led 
to a small stationary metallic plate, L, as seen 
ia tbo drawings. The plate l.i ia fastened in 
tiie door-frame and forms a jiart of the appara- 
tus which I term the " key." The said key is 
otherwise composed of a metallic spring, M, 
ouo end of wliich is made to bear against the 
plato Ij, while the other or lower end is fast- 
ened to the door-frame, the spring being fixed 
in a recess, N, made in the door-frame. 

In Fig. 5 a transverse section of the door- 
frarao is given, with the door iei)resenlcd as 
oiicti. The inner edge of the door has a sinali 
stud or [liii, O, jirojecting Iron; it, which con- 
stitutes a part of tiio key, and when the door 
is closed i)reKses against tho.'jpring .M of the 
key and bears it away from contact with the 
plate U, Ah soon as the door is opened a very 



short disi.Miec the stud will be .so moved away 
from the sjjrlng as to allow ihespiing to come 
in contact with the jdatn 1/. From tlie lower 
liart of the spring a wire, F, extends nearly to 
the lower ))ole, of the magnet and toward and 
against what 1 term tlie " spring cirenit- 
breaker," which consists of a inetallicspring, (^, 
cxtendeil upward fiom the oilier batlery-cir- 
taiil wire, l!. 

To the magnet there is applied a movable 
pi'iidnhms .•innatiiie, S, which vibrates on a 
pin. T, and liasa hammer, I", (!Xt<Mided upward 
IVcmi il and low.ard and witiiin a siiort distance 
from Ihe under side of the bell. When this 
Irammcr is at rest, or down to its lowest, posi- 
ti(m it is retained there by a stop-pin, \', 
against which the lower part of the armature 
of Lhe magnet rests nndersnch circnmslaiicc.S. 

The form and shape of the circuit-breaker 
and its relative position with lespect to thcav- 
mature and the wire P that leads from thespiing 
of the key are in the drawings. 

The top of the spring circuit-breaker is 
loiincd with a small projection, a, which ex- 
tends into jiart of the armature, so that when 
said armature is moved toward the magnet the 
projection of the cir(niitbreaker will be struck 
by the arm so as lo m<i\e tiie circuit-breaker 
out. of contact with tin! end of lhe wire 1*. 

The above constitutes lhe, alarm apparatus 
as applieil to a door. In the application of it 
lo a window llio wire 1' or anotlu-r wire, X, 
leading u)) from it, may be extended into the 
window-frame and connected with the lower 
end of a metallic spring, h, ai'ranged on the 
inside or i>ulh'y stile of theframe and made to 
bear against the edge of a sash, the said edge 
being so Jbrmed or shaped Inat while the win- 
dow is in the act of Iji^g raised it shall pres.s 
the spring toward and against the end of an- 
other wire, Y, extended down from the wire K 
before named, or is an exiension of said wire 
when the api>aratns is to bo a[)|)lied to a win- 
dow alone. The spring and contrivan(;c i\>r 
moving it, as above desci ibeil, as applied to a 
window, constitale what 1 term llu- "key."' 

The operation of the apparatus is as follows: 
While the tloor is closinl or the window-sash 
down the magnetic circuit is broken, iiecause 
the spring of the key is Ihrowii nut (d'conn.;(; 
ti(ni with the iipiier wire <if the door ov win- 
dow frame; but as soon as the door is opeiwnl 



(lU) 



or the winJow.st\Bh ,-oil so as to nllo^r tlio 
spring of tho key (o omc into contact with 
the upper wire or Ujo inctnllic pinto nt tho 
lower 011(1 thereof, the circuit will bo closoil, 
tho current of electricity being nmdo to flow 
through the circuitbrciikcr and nrounil tiio 
magnet. As soon as this takes place tho mag- 
net becomes clmrgod and draws the arniatiiro 
toward it, and tlicrcby throws the hainnior of 
tho boll against the "bell. During the inovo- 
incnt of the armature toward tiic magnet it 
throws or moves the circuit-breaker out of con- 
uection or contact with the wire 1', whereby 
tlie circuit will be again broken, soiis to dcinag- 
iictizo the rnngiict and allow tlic armature to 
fall back until the ciixMiit-brealcer again comes 
in contact with tlie wire 1", and ilicrchy closes 
the electric circuit and produces another blow 
of tho hammer on the bell. Thus a constant 
succession of blows of the hammer on llu; bell 
will bo luoduccd.

Pope at the Office of the Commissioners of Patents, with his 
Petition, on the 1st August 1853. 

I, Augustus Russell Pope, of the State of Massachusetts, of the 
5 United States of America, do hereby declare the nature of mv 
Invention of "A New and Useful or Improved Electro-Magnetic 
Alarm Apparatus, to be applied, to a Door or Windov/^, or both, of a 
Dwelling House or other Building, for the Purpose of Giving an Alarm 
IN CASE OF an Attempt to Open said Door or Window," to be as follows, 
that is to say : — 



(115) 



A.D. 1853.— N° 1795. 



Pojje's Improvements in Electro-Magnetic Alarm Apparatus. 

My said apparatus consists of an automatic or self-acting kev applied 
to the door oj- window, a set of circuit wires, an electric or galvanic 
battery and an electro-magnet connected together and with the said 
key by such circuit wires, an alarm bell hammer, and an armature for 
the magnet, sucl: armature being; attached to the hammer or a pro- 5 
jection therefroin, and finally a spring circuit breaker; the said key to 
be so made and applied to the door or window as not only to cause the 
electric circuit to be completed or closed whenever the door or window 
is in the act of being opened, but to cause it to be broken or opened 
whenever the door or window is closed. The circuit breaker consists 10 
of a spring extended up from the end of one of the battery circuit wires, 
and made to rest against the end of the other wire. It'has a projection 
on it which is extended into the path of movement of the armature, so 
that when the armature is drawn towards the magnet it shall move the 
circuit breaker out of contact with the circuit wire against which it 15 
rested. 

The armature of the magnet is a pendulous one, and so connected 
with the bell hammer that when such armature is Arawm towards the 
magnet it shall cause the hammer to strike the bell. The operation of 
the apparatus is as follows : 50 

While the door is closed, or the window sash down, the magneto- 
electric circuit is broken, because the spring of the key is thro^\■n out of 
connection with one of the circuit wires. But as soon as the door is 
opened, or the window- sash moved, so as to allow the spring of the key 
to come in contact with the circuit wire to which it is not connected, 95 
the circuit will be closed, the current of electricity from the battery 
Ijeing made to flow through the circuit breaker and around the magnet. 
As soon as this takes place the magnet becomes charged, and attracts or 
draws the armature towards itself, and thereby causes the lumnner to 
strike tlio bell. Dui-ing the movement of the armature towards the 30 
magnet it is carried in contact with the circuit breaker, or a pi-ojection 
therefrom, and moves the circuit breaker away from the circuit wire 
against which it rested. I'his breaks the circuit and demagncti/ces the 
magnet. In consequence of this, the armature is permitted to fall or 
move away from the magnet, the weight and fall of the hammer 35

causing it to do so, until the circuit breakei- springs Ijack against tlie 
circuit wire, and thereby closes the circuit, and causes another blow of 
the hammer on the bell to take place. Thus a constant succession of 
blows of the hammer on the bell M'ill be produced, the same serving to 
5 sound the alarm. 

I not oulv claim as my Invention the combination of the moveable 
or vibrating armature and the spring circuit breaker ^\ith the I)ell 
hammer, and applied and used for the purpose of ringing a IxMi, 
but I claim the combination of the automatic or self-acting key, the 
10 circuit wires leading therefrom, the electric battery or a generator 
of electricity, an electro-magnet bell hammer and armature, and a 
circuit breaker, as applied and used in connection with a door or 
window, or other contrivance for the purpose of sounding an alarm 
when an attempt is made to open the same.

moved away from the spring as to allow the spring to come in contact 
with the plate L. From tb.e lower part of the spring a wire P, extends 
nearl}' to the lower pole of the magnet, and towards and against what 
5 I term the spring circuit breaker, which consists of a niotallic spring Q, 
extended upwards fi'om the battery circuit wire R. l"o the magnet 
there is applied a moveable pendulous armature S, which vibrates on a 
pin T, and has a hammer U, extended upwaitls from it, and towards 
and within a short distance from the underside of the bell. When this 

10 hammer is at rest, or down to its lowest position, it is retained there bv 
a stop pin V, against which the lower part of the armature of the 
magnet rests under such circumstances. The form and shape of the 
circuit breaker and its relative position with respect to the armature 
and the wire P, that leads from the sjjring of the key, arc shewn in the 

15 Drawings. The top of the spring circuit breaker is formed with a 
small projection a, M-hicli extends into the path of the armature, so that 
when said armature is moved towards the magnet the projection of the 
circuit breaker will bo struck by the arm so as to move the circuit 
breaker out of contact with the end of the wire P. The above 

20 constitutes the alarm apparatus as applied to a door. 

In the application of it to a window the wire P, or another wire X, 
leading up from it, may be extended into the window frame, and con- 
nected with the lower end of a metallic spring h, arranged on the inside 
or pulley stile of the frame, and made to bear against the edn-c of a 

25 sash, the said edge being so formed or sha])ed that while the window is 
in the act of being opened it shall press the spring towards and ao-ainst 
the end of another wire Y, extended down from the wire K, before 
named, or is an extension of said wire when the apparatus is to be 
applied to a window alone. The spring and contrivance for moviu"- it as 

30 above described, as applied to a window, constitutes ^\•hat I term the 
key. The operation is as follows : 

While the door is closed, or the Mindow sash down, the magnetic 
circuit is broken, because the spring of the key is thrown out of connec- 
tion with the upper wire of the door or window frame. But as soon as 

35 the door is opened or the window sash moved so as to allow the spring

(if tlie key to come into contact wth the upper wire or the metallic 
plate at the lower end thereof the circuit will be closed, the current of 
electricity being made to flow through the circuit breaker and ai-ound 
the magnet. As soon as this takes place the magnet becomes chai-ged, 
and draws the armature towards it, and thereby throws the hammer of 5 
the bell against the bell. During the movement of the armatui-e 
towards the magnet it throws or moves the circuit breaker out of 
connection or contact with the wire P, whereby the circuit will be again 
broken so as to demagnatize the magnet, and allow the armature to fall 
back until the circuit breaker again comes in contact with the wire P, 10 
and thereby closes the electric circuit, and produces another blow of the 
hammer on the bell. Thus a constant succession of blows of the 
hammer on the bell will be produced. 

By my apparatus I dispense vvith the use of clock work or an appa- 
ratus to ring the bell through the agency of the falling of a weight or 15 
uncoiling of a spring, the hammer being kept in action on the bell 
while the battery continues to furnish electricity, and the door or 
window is open. 

I not only claim as my Invention the combination of the moveable 
or vibrating armature and the spring circuit breaker with the bell 20 
hammer, and applied and used for the purpose of ringing a bell, but 
I claim the combination of the automatic or self-acting key, the circuit 
wires leading therefrom, the electric battery or a generator of elec- 
tricity, an electro-magnet bell hammer and armature, and a circuit 
breaker, as applied and used in connection M'ith a dooi- or window, or 2.5 
other contrivance for the purpose of sounding an alaini when an 
attempt is made to open the same. 

In testimony whereof I have hereunto set my hand and seal.

MOSES G. FAKMRIl, OF SALEM, MASSAOnUSETTS 
IMPROVEMENT IN ELECTRO-MAQNETIC ALARM-BELLS. 



S|>ccilioutioM forming part of J^ctUrs 
To (lU irhom it viaij couccru : 

Be it known Unit I, Moses GEiinisn Far- 
mer, of Salcra, in llie county of Essex and State 
of Massacliusetts, have invented a new and 
nsoful Improvement on Macbiiies for Striking 
J'c'is by ElectroMaguctism; and Idobereby 
declare (bat tlie following is a f^l\\^ clear, and 
exact description of tbc constrnction and oper- 
ation of the same, reference being bad to tlie 
annexed drawings, makingai)artof tbis speci- 
fication, in wbicb — 

P'igure I is a perspective view of tbat i)art 
of tbomacbine wbicb constitutes my invention, 
termed in tbo subjoined description tbc "lib- 
erating apparatus." Fig. 11 is a perspective 
view of tlie maeliinc, showing the position of 
the bell, the hammer, the striking apparatus, 
and its connection with the liberating part of 
the machine. 

My invention consists of mechanism of pe- 
culiar construction, which is put in operation 
by electro-magnetism, and so combined with a 
train of wheel-work, cams, spring, weights, 
and a hammer, as to cause successive blows to 
be struck upon a bell any required number of 
times, the main feature of the invention con- 
S'.stiug in this, that I am enabled by its use to 
bring into action any desirable amount of 
force, either of gravity, of a spring, of cur- 
rents of air, or of steam, and control the dura- 
tion of the same by the electro-magnet. 

In Figs. I and II tbo frame of the machine 
is shown at 1 1. An clcctro-raaguet, L L', Fig. 
I, is placed in a horizontal position near to one 
end of the machine. An upright bar, c, hav- 
ing its center of motion upon the rocker-sliaft 
J is attached to tbc armature K of the magnet. 
The top of the bar c is made sufficiently broad 
to allow the end of the arm N to rest upon it 
at b, the opposite end of the arm N being firmly 
affixed to the rocker-shaft O O, which is sup- 
ported by the upright stands C C. To the 
same shaft O O there are also atfixed three 
arms or levers. A, P, and/. A isan arm wbicli 
may be about ten inches in length, having a 
weight, a, at its upper cud. This bailor weight 
isnot vertical with the rocker-shaft O, to which 
it is attached, bwt is inclined at such an angle 
as to insure its fall whenever the horizontal 
bar N is not sui)ported by the upright bar c. 
The distance through which the bar « is al- 
lowed to fall is regulated by the restW. The 



Pulont No. 8,9it0, fluted Miiy 4, IBM. 
aru P may be two or three inches in length, 
and is aflflxed to the rocker-shaft O in such a 
position as to act upon the end of tbo horizon- 
tnl latcb-sbaped detent d and raise it from the 
pin or stud e. The detent d is supimrted atone 
end by a stud, V, upon which it turns. The 
Oi)posito end carries .^ pin, Q, which falls upon 
another pin or stop, II, attached to tbc stand 
C, and prevents the detent d from falling 
lower than is necessary. The arm /, also 
firmly fastened to the rocker-shaft O, has at 
its lower end a stud or pin, D, placed in sucb 
a position as to come in coitact with the cam 
g g, as hereinafter described. 

The horizontal shaft E E, which is supported 
in the stands F F, placed upon opposite sides 
of the frame I I, carries the dog S, the pinion 
G, the gear T, and the cam or wi|)er g, all of 
which are firmly secured to the shaft by splines 
or other suitable device. The cam g may be 
of about the same form shown in the drawings, 
its shape being such as to insure (by the inter- 
vention of the stud D, the bar/, and tberocker- 
shaft O) the elevation of the arm and ball A 
a to the required height, and at tbc same lime 
allow it to fall upon the rest W. 

The pinion U, placed below the gear T and 
driven by it, gives motion, by means of the 
borizoi.val shaft r, to the vane or fan /*/»', which 
may be placed outside of the frame I. The 
bar 1 1, to the opposite ends of wbicb the vanes 
h h' are fastcnd, turns freely upon the shaft r. 
"^t carries a pawl, Y, and spring X, so placed 
ibat the pawl may play in tlicratciictZ, which 
is firmly fixed to tbo shaft. 

The pinion G forms a connection between 
the mechanism above described and the com- 
mon strikiugapparatusol a tower-clock. Upon 
the latter machine I claim no imi)rovcment8, 
as my invention relates exclusively to the lib- 
erating apparatus, as hercinlicfore stated. 

In Fig. II, which shows the general con- 
strnction and relative position of the principal 
parts of the machine, 'R represents a section 
of the lip of a bell; JI, the hammer; M, the 
weight; ii, the crank, by turning which the 
weight is wound up. 

Tbo pinion G, Fig. I, plays in llio gear T.

between the striking [tart of the mechanism 

and tbo liberating apparatus.

siicb as to allow time for one stroke of tbe bam- 
inor n))on tbo bell at cacb of its revolutions. 

To set tbc inccbanisni bcrcin described in 
motion a current of electricity, generated by 
a suitable battery, is i)asscd tbrougb tbo coils 
of tbe magnets L L', tbo armature K is at- 
tracted to tbe magnet, tbe nprigbt arm c moves 
witb it, tbe borizontalarm N is no longer sup- 
ported, and tbc weigbtcd arm A falls over un- 
til stopped by tbe adjustable rest W in front 
of it. In falling tbe lever P raises tbo latcb- 
6b'>j>ed detent d. Tbc dog S, carrying tbe pin 
e uttacbed to tbe same axis witb tbe cam g, 
and connected witb tbe train of wbeelsof tbe 
strikingmacbinory, is tbusliberated and begins 
to revolve. In sodoiugtbe cam </ revolves and 
swingsforward tbe bar/attached fotbcaxisof 
tbe falling arm A, whicb is tbus raised to its 
original position. Tbc borizont^l lever N

leased, tbe detent d falls and comes in contact 
witb tbo pin c,tbns arresting tbe dog S at tbe 
end of one revolution. Tbisoccupieboncor two 
seconds, and iu tbo meantime the weigbt M 
bas fallen a abort distance and a single blow 
bas been etrnck by the hammer upon the bell. 
If tbe armature K were not released from tbe 
attraction of tbe electromagnet tbe horizontal 



lover N would not catch at 6, Rnd tbe machine 
would continue to strike until tbecircuit-infln- 
onciiiR electro-niftgnot wim Intcrninlcd. 

Tlie re<l lines in the drawings snow the po- 
f-ition of a spring, 4, of india-rubber or other 
clastic material, one end being attached at 5 to 
the falling arm A, and the other end fastened 
to tbo frame of tbe machine, as at C. As tbe 
arm rises tbe spring is eitended. As it falls its 
velocity is increased by tbc contnc lion of the 
springs 

It is obvious that either the weight (( or the 
spring 4 may be used separately, or their ac- 
tion may be combined, as above described. 

I claim as ray invention— 

The cotnbinatiot), substanttally as bereiu set 
forth, of the electro-magnet and armature, or 
its electromagnetic equivalent, with tbc tail- 
ing ball or spring and the detents, and tbe lift- 
ing-cam or its equivalents, so arranged that 
when tbe ball is supported by the armaluro a 
slight force only of the electro-magnet is re- 
quired to trip the ball, which ball in falling 
requires sufficient momentum to produce much 
greater mechanical effects than the magnet 
alone, tbe velocity of tbe ball in falling being 
still furtheraccelerated by theforceof aspring, 
if desired. The power tbus obtained 1 use iu 
tbe manner and for the purpose herein de- 
scribed.

is fnlly described and represented in tlie fol- 
lowing spceilication and tlie accompanying 
drawings, of wliieli — 

Figure 1 reiircsents an elevation of a door 
and window and my apparatus as applied 
thereto. Fig. 2 is a vertical and tiansvcrsc 
section taken tliiough tlics|)ringcircnitl)reak- 
cr to be lieieinafter described. F'ig. 3 is a ver- 
tical section of tLe aj)paratus hereinafter 
termed the "key ^ as applied to tlie door. Fig. 
4 is a section of tlie same as applied to tlio 
window. 

In the said drawings, A represents a tloor, 
of wbicli ]3 is tlic frame, tlie same being shown 
as fitted into the wall D. 

Vj and F arc wiiidow-sashes of a window- 
frame, G. II is an elcctro-mugiiet, fastened to 
the side of the wall in a convenient ])osition, 
and having a bell, I, arranged over or near to 
It. One of the pole-wires leading from an elec- 
tric battery is seen at K. It extends to and 
winds around tlic inagneL and passes upward 
over the bell and window-frame, and thence 
downward into the door-frame, where it is con- 
nected to a small stationary metallic jilate, L, 
ns seen in the drawings. This plate L is fast- 
ened to the doorframe and forms a])artof tlio 
apparatus which I term the "key." The said 
key isotlierwis(! composed of a metallic spring, 
M, one end of which is made to bear against 
the jilate I;, while tlio other or lower end is 
fastened to the doorframe, the spring being 
ll.xed in a recess, N, made in the doorframe. 

Ill Fig. a transverse section of the door- 
framo is given with the door rciircsciitiMl as 
open. 

The inner edge of tbc door lias a small stud 
or pin, O, projcetiiig from it, which constitutes 



a part of the key, and when the door is closed 
presses against the spring M (,r the key and 
bears it away from contact with the plate L. 
As soon as the door is opened a \ery short dis- 
tance the stu<l will be so moved away from the 
spring as to allow the spring to come in con- 
tact with the plate ];. 

From the lower part of thes|)ringa wire, I', 
extends nearly to the lower ]>olc of the magnet 
and toward and against wiial I term the 
"spring circuit-breaker," which consists of a 
metallic spring, (J, extended upward from the 
other battery circuit wire li. 

To the magnet there is apidied a movable 
pendulous aimature, .S, which vibrates on a 
pill, T, and has a hammer, U, extended from 
it and toward and within a short distance from 
the under side of the bell. When this hammer 
is at rest, or down to its lowest position, it is 
retained there by a stop-pin, V, against which 
the lower part of the armature of the magnet 
rests under such circumstances. 

The form and shape of the circuit-breaker 
and its relative jiosition with respect to tho 
armature and the wire P, that leads from the 
spring of the key, are shown in the drawings 

The top of the springcircuit-breaker is formed 
with a small ])rojection, «, which cxteuds into 
the path of the armature, so that when said 
armature is moved toward tho magnet the pro- 
jection of the circuit-breaker will be struck by 
the arm, so as to move the circuit-breaker out 
of contact with the end of tho wire 1*. 

The above constitutes the alarm apparatus 
as applied to a door. In the application of it 
to a window tho wire I', or another wire, X, 
leading u() from it, may be extended into tho 
wiii(U)W-franio aiul connected with tho lower 
end of a metallic spring, /;, arranged on tho 
inside or imllcy stile of tlie i'rame and made to 
bear against tho edge of a sash, tho said edge 
being so formed or sliai)eil that while the win- 
dow is ill the act of being raised it shall press 
the spring toward and against the end of an- 
other wire, Y, extended down from the wire 
K before named, or is an extension of said 
wire when tho aiiparatiis is to be applied to a 
window alone.

IMPROVEMENT IN ELECTRIO OIROOIT-BREAKINQ CLOCKS. 



ttfet St^fiiih tfltrrtb lo in Ibfst Jjtttrs opulent nnb miiliing i!:irl b( tbt sanu. 

TO ALL PERSONS TO WHOM THESE PRESENTS SIIAi.L COME: '^ ' - ,.'.v 

Bf it known that I, EnwiN Holmes, of the cilj, county, aiiil Stale of New York, liavo invented a new and 
useful ElectroMsgnetic Circuit-Brciikiiig Clock; ond I do liorcby declare the bbido to be fully described in the 
following apccificnlion, nnJ represented In the Rccorapaiiying drawings, of which — 

Figure 1 is a front cleTalion of a common clock or timo-pieco provided with a circuit-l-caking apparatus 
in Bccordanco with my invention, llio face and hour-denoting figures or characlera of the clock being exhibited 
in red lines. 

Figure 2 ii a section of the breaker-wheel and its spring. 

Figure 3 is a vertical and tranivcrie section of such brcukor-whccl and its adjusting wheel. 

Tim piirpo.^e of my invcnlion is to effect iho brcnking of an electro-tnngnclio circyil at »py particular time 
of the ilnv, and I-; keep it broken for a determined period thereafter, if desirable. It may also be constructed 
for closing a nrcuit nt atiy (lefinilo titno of the day, ond for keeping it closed during such period or part of such 
day therrafliT as may be desir'.' le. 

My inv<-iitiun is sjiccially designed (o be used with the circuit of an cloctro-magnctic alarm apparatus, par- 
ticularly such ns was patented by Augustus B. Pope, June 21, 1853, in which case it would be designed to 
break the circuit at an early period in tho morniDg jusi previous lo the time ncccisory for opening tho house or 
one of ihi- windows or doors thereof included in the circuit or to which the circuit may bo applied. By ro 
breaking the circuit, tho soumling of the alarm will be prevented whenever such door or windovr may bo opened, 
■ nd thus persons in ihc house, whom tho alorm, if Bounded, would awaken, con remain asleep. Therefore it 
will be seen ihnt ihc porticulor object of thus breaking the circuit is to enable a person at the proper tinic to 
open a "lonr or window in the circuit without at the same time causing the alarm to he foui\dcd and awaken the 
inmates of ihc house who m:iy bo desirous of remaining asleep. 

In ihii ilruwiiigr,, A denotes a clock of oidinnry eonstruclion, (i bcin^ lie hour hnnd and 6 its minute li.iiid. 
(Jn the orhni- of the hour hand rt, ami concenlricnlly thercwiil-, I arrange what 1 Iciin the hrcakernherl B, 
which, by a xlinrl tubular ahoft, f, is connected with iin udjusling-wheel, C, on wlioso foco arc marked the ngiins 
or signs reprc^enlir.g the twelve, hours. A portion of the [.riiphrry of the wliCel B, vii, that marked ,1, ii :\ 
nf.n-coiHlin.lnr nf gb'dricity, tho remainder of the wheel being yiado of metal. On iho said periphery of ihu 
wheel B, a iiulnllic tpring, 1>, bears, it being extended fiuin a circuit-wire scrcwconncctien./, projected from 
anorui,</, "IimIi i«.ccuredor fixed to ihe melnllic fronie /. .^f the clock, and should be a non-ionduclor of 
■elcclrieily. Hih of the battery wires of Iho cirruil, ni, llmt nmikrd E. leads into and is to he fi.tod to the 
connecliun/. Tli- conlinualinn of Iho circuit is hy a une, 1"', leading from another scrow-conuection, (', fi.i'd 
to the frame //. Whilr the (Spring D is in conlinl Milh ihe nielallic part of the perijihery of tho breaker 11 tho 
circuit will he ilu-.-d, but a.« soon as it comes into an<l while it may renioin in contact with tho [lart <^, tho 
circuit will Ic liuiken or open. When tho meridian hour murk, v ir.. XI I, of the odju.«ling-wheel is in its highest 
position, the ipiing 1) sliouUl be in conlacl with one extremity of the part d. Tho circuit breaker B and its 
adjusting-wheid shmild revolve together on tho arbor of the hour hand, with friction Midieicnt to enable them 
to he carried around or revolved by it, ai.a lo ho Inrned at other limcJ Oil tho arbor in order to adjust the part 
d with refeu;.eu to the hour hand." In order lo «(t the breaker B so ai to cause the current lo ho broken at 
any p:irli.ul.ir hour, llie number or charncler designating such hcjr on tho wheel C should ho brought around 
inlo jirklapn,iii.,n will, llie h-.ir lund. When the hour hand may reach that particular hour on the dial, the 
pnrl >( will be brought inlo conlaet with iK' spring and the circuit will bo hr-.ken. 
What I claim as my invention, i? — 

The coinbinalion n» well os ihe arrangcmenl of ihc circuit-breaker II, Us adjuster C, and tho spring 1), "ith 
a clock or -imc-piece A, and an elerlric or'eloclro-magnetic nrcuil, the whjlo being suh.slanllally as and for the 
purpose as hereinbefore, p. elfied. KimiN HOLMES.

IMPROVEMENT IN ELECTRO-MAGNETIC ANNUNCIATORS. 



SpocKlcatloii foriiilnf; part of Letters Pntoiit No. UH/i-Tl, dutcj AuKiiat22, 1871. 



To all whom it may concern: 

Bcitknowii tliatl, Ki.isHA Gray, of Cliicngo, 
ill iLc county of Cook and StjiUMif IlliiioiH, liavc 
invented a liew and useful Iniiuoveinent in Klee- 
tro-Mn^a'tic, Annunciators; and 1 <lo Iiereby de- 
dare tlic following to he a fnll^ cl(tar, anil exact 
dcMcription Miereof, wliicli will enable otlieix 
Hkille<l in the ait to wliieli my invention apper- 
tains to make and use tlie same, refereiu'c beiii',' 
ba<l to tlie aecomiiaiiying di-,i\\in>,' formiii},' part 
of this sp(!cilication, in which — 

Figure I is a toji view of my invention. Fig. 
li is an inveited transvei-se longitudinal section 
of the same,. Fig. .'{ is a side elevation taken on 
line rt f(. Fig. 4 is vertical longitudinal section 
on line d il, and Fig. .5 is an enlarged detached 
Bcetion of the knoli ciniiloyed in levei-sing the 
electric cuneut. 

Similar let tcrsof reference indicate e:)nes|)ond- 
iug i)arts in the several ligures of the drawing. 

The object of my invention is to ]U-ovide an 
aiiniinciatorfor the use of hotels and otiier simi- 
lar public buildings, by which the number of the 
i-ooin or rooms from which the c^ill is made may 
lie indicated upon the dial; and the. iin]»rove- 
mcnt consist.s in an electro-magiietie arninge- 
ineiit eommunii-ating from the ai>ailmeiit witli 
the dial, a description of which in det^iil will be 
liereiiiaft«r fully given. 

ill the accompanying drawing, A'leiiresents 
the case, which may be as shown or of any known 
form, which will receiv e the o|terating parts of 
the instrument. U is a metal plate, wlii(;li is firm- 
ly allixed to the inner side of said (-ase, and upon 
which is mounted the electro-magnets 1) I)' I)". 
Each limb of said magnets is connected at its 
opi)Osit<' ends from the plate by inet^il heelpieces 
a an firmly allixed to the aibor or bearing (»f the 
same. EK' l^" are shafts, oik^ end ol' which have 
al)earing witliiii plate M, and are pivoted at the 
o])lM)sit<! end to or u]>on set-screws il d <l, which 
are secured within stnipsri, by which the; same 
are liehl in )>rop<'r adjustment. Allixed npcni 
said sliafts, between jilate B and the end of the 
magnet-s, are steel needles or armatures c c >\ 
which aie i)roperIy hardened and magnet iy.ed. 
Haid needles or armatures are so arranged as to 
have an aiitonialie tilting movement, by the re- 
ciprocal it)ckiiig movement of the shafts, iin- 
jiailed theretx) by the electrical ciiirent from th<i 
uiagiietH. Attaclied to plate IJ are lugs///. 



which arc so airanged as to prevent the said ar- 
matures from coming in cont;i(-t with an<l against 
the poles of the electro-magiu'ts as the s;imear(i 
tilted by the eU^ctrical current. Said lugs are 
usually made of cork, but they niay be made of 
any suitable material. F I'"' F" are light metal 
indicating- pointers, which are liiiiily aflixed to 
the outer ends of said arbors in front' of plate It 
immediately under the figures marked upon the 
dial. Attached to the outer side of the. cast; are 
metal springs (1 (i' and II II', whi(-ii are bent in 
proper siiape to bring their ont('r ends in contact 
with and against metallic rings 1 and 1' allixed 
upon the knob-spindle .1, whicrh is secured to the 
|>roiect ing portion A' of tin- case. Said rings are 
insulated one fioih the other, and their perijdiery 
<-ut into two se|iarate |)arts, forming in each a 
long and short section. The short section of ring 
I is connected to the long se(rti<Mi of ring 1', and 
(he short section of ring 1' is connected to tlm 
long section of ring I, by which the electri<;al 
current is conveyed from one to the other. Af- 
lixe<l to the short section of ring 1 is a pin or 
jiivof, //, to which is attached a curved spring, /(, 
.so an-.inged as to come in contact with and jiass 
ovei- jioints L, iM,and N, which are iiermaiieiitly 
attache<l to projection A' of the case, as said knob 
or commutator is revolveil, the s;imc l>eingsoar- 
i-.inged as to admit of a rt'cipnK-al seniiaiinular 
rotary movement. .Vttuched to and upon the 
kiiob-s])indl(^ <l of the commutator is a coiled 
spring, /', which is .so arninged as to force the 
s:iid knob back to its |ut>)>er position as the s;iine 
is ixitateil partially around, and firmly holding 
the sjiine against a stop|iin, /, secured in the said 
projection. Alllxe<l to the said ]>oiiits L, M, and 
X are wir(!S K, S, and 'J', which are each attached 
at<ine(;nil to the magnets 1) D' D", the, opposite 
ends of each leading to ditl'erent rooms having 
inimb(;rs correspoMding with th(^ numbers indi- 
cated upon the dial. Within each sepanite i-oom 
is seemed a ciicnit-closer, the mani|>iilati(Mi of 
which <'aiises a contact between the wire c<iin- 
iiiiinicating with the room and the common re- 
tiiriiwire iii. Oiu' end of each wire K, S, andT 
is soldered to the core of the magnets D 1)' J)", 
which are in direct conta<t with the plate 11. 
Allixed to the core of the magnet 1) is a wire, h, 
which communicates with spring II. l''irmly af- 
llxe<l to s))riiigH (! t!' are wires O O', which are 
conne(;ted witli the [loles of u giilvanic battery.

Tlic oitcratioii of my invention is as follows: 
As tlic <)('c,ii)i;mt of room No. 1, for instiiiico, 
m:iiiiinil!it<'s tlio circuit-closer the cloc.triciil ciii- 
r(!iit will iiass from wire O' through R|iiiii;r (}',

already in the aiijiroximate i)oles of the needle- 
aruniture c, hence a mutual repulsion takes jilacc 
hetween the ajiproximatc )>oles of the magnets 
and a mutual attnu-tion hetween the more dis- 
tant ones, tlic oliject of which is to lilt needle r 
to a reversed jiosilion, which carries iioiiitcf 1"

a Itell secnre<l ujioii the return-wire. 1'he. call 
having been made and the. nundierof the room 
noted, it now remains to restore the jiointer to 
its former position, w hii^h is done. l>y turning the 
knob of tlic commntatoi' until spring // makes a 
contact with point N, thus changing springs 1111' 
from the short s<'ctioris of lings I and J', which 
brings spring 11' in direct contact with spring (!', 
and sitring II with s[)ring (!, by which meansihe 
electrical curi-ent )ia.'<.s<'s from wire () to and 
thiiiugli spring G', thniugh the long section of 
ring 1', slnnt section of ring f, spring II, metal 
l>oiiit N, wire K, magnet I), plate 11, spring II, 



long section of ring I, sjiring G, and wire O' to 
the pole of the batteiy ; thus the elec^trieal cur- 
ic.nt will pass through magnet 1) in a reverse di- 
icction from that which was inodnced by the 
manipidation of the |-o<nn circuit-closer, by which 
a r('ver><e ed'ect is jiroduecd upon needle f, which 
rest(n'es jtointer l"' to its original position. 

The same o])eration may be icpeat-ed in alike 
mannci' with any other nundjcr which will ]iro- 
dnce a corresponding I'esult. 

IIa\ing thus desci-ilie(l my invention, what 1 
claim as new, and desire to sccme by Letters Pat- 
ent, is —

To nil whom it mntj concent: 

]t(i it known tlii'it I, Ki-isnA Gkay, of Clii- 
c(\;;(), in the county of Cook and St;ito of Uli- 
nol.<<, liavc invented ccrtnin new and nscful 
Juiiirovenients in IvIcctriciU Annnnciatois. of 
whicii tlic foliowin{r i.s a full, clear, and exact. 
dc.'<cri|)tion, Avliicli will enable others skilled 
ill the art to whicli my ii vcntion aii|)ertains 
to inako and ii.-^e the siinio, reference lieins: 
had to thc! acconii>anyin^' drawing, forming a 
pait hereof, and in whicli — 

Fi/,'iiro 1 i.s a froiitelcvalioii of an aniiiinci:" 
t(ir cmlxxlyiii;; my invention. l'"i;j. 2 i.s a rear 
elevation of tlie same; I'^i^'.^, a vertical cross- 
section of the plate to which the ]iolc.s of thc 
magnet are attached, certain other parts being 
shown in elevation; and Fig. 4, a rear eleva- 
tion of certain ]ia its shown in Fig. li, the mag- 
nots being removed. 

Like letters of reference indicate like i)art.s. 

Jly object is to simplify and imiirove the con- 
struct ion and operation of that cla.Hs of electric- 
al annnnciators usually employed for sending 
(^alls from thc rooms to. the ollico in hotels and 
other li(iildings,aii<l forsiudlar purjtoses; and 
to that end my invention consists in certiiin 
novel fc;itiires, siibstjiiitially as hereinafter de- 
scrilKid, relating to tli(< method and mciinsem- 
pIo3'e(l for the i)iiri>OH0 of aceomplisliing the 
object above set forth. 

In thc drawing, A represciit-s thc case of the 
nnnunciator. 'riienumerical characters in Fig. 
1 designalo the various rooms in the building. 
]1 is a bniss plate attJiched to the case. C C 
arc ordinary electroinagnets, tlu^ [loles of 
which are attached atone end to the plate H. 
]) \) aio soft-iron armatures, each pivoted to 
the jilato, as shown at d d. J)' I)' are arnni- 
ture-levers, rigidly attached to thc armatures 
D 1). The outer or free ends of these levers 
are made hook-shaped, as shown, d' d' are 
sloppiiis, against which the armatures icst 
wlicM in their normal position, a sundl space 
then existing between the arnuUiires an<l the 
jioles of tliemagnets. 'J'he hook-shaped arma- 
luie-levers are the essential novel features in 
connection with the armatures. lO 10ar(^Mpill- 
(lles passing freely through the plate li, and 
to the onler ends of these index -hands or 
]n)lntA'is F F are rigidly attached. These 
spliidloa uro capable of a free rotary luove- 



mout. (! <i are irregularly-shaped arms, rig- 
idly attached to the spindles JO JO. The form 
of these arms is such tiuit thoy nr.iy Ivo on- 
gaged by the aruniture-levers when the arma- 
turea rest against the stops d' </', and sucli 
that they may also then re-st iie;irly against 
the armatures, as is plainly shown in I'^ig. -1. 
H H arc vertiwilly-slidiug bars inovided with 
the lateral arms A /i, extending sutUciently for 
contai:t with the parts G G when thc said bars 
are moved for thc imrpo.se of re-sloriug the in- 
(h/xliands lo their normal [lositioii, and sudi- 
eiently to sui>port the parts G (J when tlielat- 
U^v are not engaged by thc levers D' J)', as 
will hereinafter more fully appear. The bars H 
II rest on the horizontal bar 1, pivoted at each 
end to the i)arallel inclined arms .1 J, the lower 
end of which latter are pivoted to thoplat^^H. 
The bar 1 rests on the crauk-arm Jv, and K' is 
a crank arm or lever arnmged e.xternally to 
the cii.sc, and attached to the same nxl or shaft 
to which the arm K is fastened. /.' is a stop- 
pin, on which the arm K rests. The battery 
may be arranged in any convenient idaco. 
One end of the wire of each magnet iscarrie<l 
to an iusidated biuding-i>ost, L, there being 
one of tlie latter to each magnet, and the other 
end is carried to the heel of the .same magnet, 
thus connecling the latter with the plate 15. 
A circuit-wire is carrie<l from the plate B to 
e;ieli nxim, and amither from each room to a 
correspon<lingbin<ling-post, \j. These larcuits 
may be eonnectc<l by means of a common key 
arranged in each room. The battery- wire may 
be arranged in the eiixuitin the usual nninner. 

When the key in the room No. 1, for exam- 
ple, is depressed, thecurrent will pass through 
a eon-espoiidiug magnet in the annunciator, 
and the arnmlnio of this magnet will bo at- 
tracled to the poles of the same magnet, liy 
this means the lever of the armature so at- 
tracled relea-^es the piece G, operating in ciui- 
neetion with it, and this iiieee falls upon tho 
next lower arm /(, and, in falling, moves acor- 
respou<ling pointer, F\ toward the llgnro 1, 
thus iudii-.atiiig Ihat a call is made from room 
Mo. 1. A call from any other unim may bo 
nnule in like nniuner. 

Jn order to set tho indicator alter one or 
nioio calls have been made, tho lever Jv' is 
80 uio\ed us to raise the bar 1, thus also rais- 



(215) 



169.05T 



hip the Imrs II II, and lifting such of the pieces 
O G as may have fallen upon the arms h h, 
tliuspnshinptlio armatures from the poles, and 
allowing the arniatiirelevcrs to engage the 
\tarts G G and hold thorn up, thereby restor- 
ing the point^'rs to their normal iwsition. 

When the lever K' is released the annun- 
ciator will bv set, it being understowl that the 
circuit throiigii tlio magnet is broken by re- 
loiwirig the key in the room, Cnrtuins may 
bo cmjiloycil instead of the pointers, and viv- 
rious niCHiia may bo U80<1 to restore the parts 
G G to their engagemont with the armature- 
lovers. The normal jMisitiou of the armatures 
is against the jiins d' d', 

I It will bo observed, from the foregoing do- 
Rcription, that no sjirings are emi»loyexl in 
connection with any of the moving parts; 
also, that all theiiiecesG G are slightly moved 
each time any of them is set., thus preventing 
the spindles to which they are attachetl from 
becoming rigidly set on account of rust, dust, 
or hardenc<I grease and grit, and keeping 
them in free working condition at all times. 
The armatures are i)U8hed from their jwlea 
through the instrumentality of mechanism 



employed to restore the pointers to their nor- 
mal position. 

Having thus described my invention, what I 
claim as new, and desire to secure i)y Letters 
Patent, is — 

1. Thearmaturo I), provided with thchookcd 
levers D', in combination with the tilting piece 
G, rigidly coi)necte<l to the index, and con- 
structed and arningcd substantially as shown 
and described, to bo struck by the restoring 
mechanism, to strike the said armature, and 
to bo engaged by the said lover, us and for tlio 
purposes sot forth. 

2. The combination of the pivoted arma- 
ture ]), provided with the hooked lever 1)', 
the tilting piece G, rigidly attached to the 
spiiulle or sleeve of the index, and the sliding 
bar II, provided with the extensions /( h, tlio 
I)icce G being con8tructe<l and arranged to bo 
struck by the sjiid extensions, to strike the 
said armature, and to bo engaged by the said 
lover, all substantially as and for the purposes 
8i)eciflod.

Figure I represents a froiit elevation of luy 
annunciator; Tig. 2, a perspective view, show- 
ing tiio construction of the annui\ciat«r and 
Hie manner in which it is connected with the 
interior of rooms in the hotel ; and Fig. 3, a 
sectional view of the knob and its attach- 
iiients used for clo.sing the circuit in each 
room. 

The nature of iny invention coiisi.sts in the 
construction and oi>eration of the mechauism 
Lcrc-aftcr described, by which the curtaiu or 
blind i.s moved to indicate the numbers on the 
dial of the annunciator designating the room 
the signal is given from. And it also coiiaist.s 
in the combination of the iicrniaiicnt magnet, 
and the wires connected with it, with the mag- 
net A, HO as to shunt said magnet, as Iier^fter 
described; and in the (Ireatarni meclianisin 
arranged in each room, so that, by the expan- 
sion produced by heat, a permanent circuit is 
forinc<l, which gives a constant alarm, as here- 
after described. 

To enable those skilled in the art to under- 
stand how to niaiuilacturo and use my inven- 
tion, I will juoceed to describe the sanio with 
particularity. 

The same letters of reference refer to the 
corresponding parts in the dilleront ligures. 

In the ;uinc\eil drawing, It and (J reiuesent 
a portion of the interior of two rooms and the 
annnnciator, which is located in the ofllco of 
the hotel, with three coil- magnets, one of 
which. A, is a geneial magnet connected with 
all the others, and (ho other two, It' and C, 
are special magnets to each room, Hand (), 
and are connected directly by wires each with 
it-s particular room. I have as many special 
mag""'? as I have rooms, each magnet being 



connected by a special wire with its particular 
room. 

In the annexed drawing, \V is the sjiecial 
magnet for the room 11, and C for the rocnn (), 
I) is the galvanic battery, one pole of which 
is connected, through th(^ thumb screw V. and 
wire F, to the coil-magnet A, that being what 
I call the general magnet, on account of being 
connected with all the special or room mag- 
nets. It is connected with the special or room 
magnets by the wire 11', wiiich connects it 
with the plate I, with which all of said mag- 
nets are connect-ed, as hereafter described. 

The magnet C has one en<l of its wire .) at- 
tached to the plate 1, while tli(( other end is 
connected with the knob M in the room U, 
and the wire K of the magnet It' has one end 
also attached to the jdale I, while the other 
end is coniiee.lo.d with the knob M in the 
room 15. 

There is also a wire, N, which is connected 
with one pole of tlio battery through the 
tlinmb screw I,, and is connected with the knob 
M in each of the rooms, so that, when the knob 
M is pulled, !is hereafter described, the circuit 
is comitleted lliroiigh that ro(mi and Hie an 
iiunciator. 

There is a vibrating iirmatnre,0, pivoted in 
the center, and located between the iioles of 
each coil-maguet in such a manner that wlien 
a circuit is closed through any one of the 
magnets its armature will bo viliraled by the 
ends of the armature being drawn to the poles 
of the magnet. 

To each of tln^ armatures connected with 
the special or room magnets there is attached 
an arm or projection, I', which, when the arma- 
ture is vibrated by the closing of the circuit, 
strike.'^ against the vibrating arm (^ which 
sujiports the blind or <nrtain U, opposite the 
number on the dial 8 correspomling to the 
number of the room through which the circuit 
is closed. 

'J'ho arms (^ are Kopivoi..'<l to the plate I 
that they will sl^iiid in a i.osition to hold the 
blind U directly behind the numbers on the 
dial S till they are swung. by the iiroJectioiiH 
r, as above described, from behind the num- 
ber to the position in Fig. 1.

r.i iiiaturo O of tlio general iiinpnot A. so that 
wlicn tlio nrniatiiro \a vibrated, as auovc div 
Rc.ribcd, it cmmos tbo lianimer to strike tlie bell 
J)' and give an alarm; and, as tbo gciioral 
inngnot A is connected with all the other mng- 
iict8,wlieiic\er the circuit iscompleted Ihroiigh 
any of the s|>eciftl niagnots it also passes 
through the general magnet A, and cansos tlio 
boll to strike, so that the boll strikes and gives 
tho alnrni at tlio same time that the blind falls 
from behind tlic number on tho dial indicating 
tho nuniber of tho room in which tho circuit 
was comiilotcd. 

Tho bamnierhandlo A' passes through a 
notcb ill tbo vibrating arm K', and it is so ar- 
ranged that Just before tho liammer strikes 
tho bell the handle A' causes tho arm E' to 
vibrato and close a circuit through the wires 
F' and II' and the points at I', wliicli shunts 
tlio magnet A and roliovos tho attraction on 
tho armature, when the spring .1' raises tho 
liitninicr. 

The permanent mngiiot K' iiolds tho point 
I/, which is thrown against oiio of its arms by 
tho vibration of tho arm K' as tho shuntclr- 
cuit is closed, and lioldH said circuit closed 
until tho hammci-handlo is raised nearly its 
fiiii Miroko, when it strikes Ibo side of the notch 
in Iho vibrating arm }<)' and raises it, which 
opens llio shdut-circuit, and tho circuit is 
thrown through tbo magnet A again, and tho 
strokes of tho hammer aro repeated so long as 
tbo circuic through the room is kept closed. 

When there is no circuit closed through any 
of tbo rooms tho spring J' raises tho hammer, 
and tho point or armnturo 1/ ia liold by tho 
permanent magnet, so that tlio shuntcircuit 
is held open till the current has passed through 
the inagnot A and caused a stroke of tlio liiun- 
mer, as abov6 described. 

Tho shunt abo\'o describe<l also serves the 
additional jiuriKise of increasing the strength 
of tho circuit through the special mngnct of 
tho room in which the circuit is closed. When 
the circuit is first close<l it passes through tho 
magnet A, a,s above described, being weak- 
ened by tlie resistance of that inngnet. As 
soon, lidwever, as tbo circuit through tho 
Hhuiit is oinsod, tho lesiHtance of the iiiugnul, 
A is avoided, and tho force of tho circuit in 
tho Hpecial iiiiigiiel cnriespoiidingiy liicionHed, 
HO that if at (list tho <'iirrenl is not slroiig 
enough to vibrato the armature of the s|wH;iRl 
magnet and lilt tho blind or curtain, as above 
described, tho increased force will ahvtiys 
effect it. 



Tbo circuit ia closed in tho room by pnlling 
tbo knob M and bringing tbo pin a, which ia 
conneclo<l with the wire N through the sjnndlo 
of tho knoll, in contact with tho wire. T. When 
tli(\ knoll M is rulonaed It is thrown back in 
place by tho coll smlng h. c Is a wire or rod, 
0110 end of which is (:onllecU^d with the wire 
N, niid liio (iliicr end with tbo bur c. This rod 
is made of metal, which expands when boated, 
and is so connected with tho bar c that it holds 
tho points at/ apnrt till it expands, and when 
It expands tho spring /; draws tbo points to- 
gether and closes the circnit. 

If the room becomes sufTlciently hot to ex- 
pand the wire c, and the wire can bo so con- 
structed as to expand and close tbo circuit at 
any desired increased temperature, the circuic 
is permanently closed and a constant alann is 
given at the ofOce by tlio striking of the boll 
D', as above dej?cribcd. 

A single signal is given by tho occupant of 
a room by pulling the knob M and releasing 
it; but, in case of a flroin a room saDQciently 
hot to expand the wire c, the circuit is perma- 
nently closed and a continuous signal given. 

The dial S of my annunciator is an ordinary 
glass, covered on the inside with an oparjuo 
substance, such as paint or paper, excepting 
the outlines of tho flgurc-a indicating tbo num- 
bers of tho various rooms, tlioy being made in 
tbo opaque substance and seen through tho 
glnsa, tho blinds behind tho figures being of 
the color of the opa(pio covering of tbo glass, 
and tlio figures to bo obscure till tho blinds aro 
tilt«d, ofl above descril>cd. This is n clioaj), 
simplo way of constructing tbo dial, and causes 
the nuniber of tho room from whicli tho signal 
is given to bo shown very distinctly. 

ijy pivoting the armatures O they can be 
vibrated, ns above described, without over- 
coming a weight or tho force of a spring, which 
baa heretofore been objectionable on account 
of the electric force reqnired to move the ar- 
mature. 

Having thus fully described tboconstructioii

I claim, and desire to secure by Letters Pat- 
ent, is —

DESIGN FOR ANNUNCIATOR-DIALS. 

Specification foraiing part of Design No. §,999, dated February lu, 187C; application tiled JanQnry 3, 187C. 

i[Tcrni of Patent 14 years.] 



To all whom it may concern : 

Be it known tiiat I, Charles \V. Lewis, 
of the city of Chic.if^o, county of Coolc and 
State of Illinois, liave inventeil a Desifjn for 
a Face or Dial of an Annunciator, of wliicli 
tlic following i.s a specification : 

The nature of my design is fully leiuescnteil 
in the accompanying drawings, to wliiclt lef- 
eieuce i.s made. 

A represents the face or dial plate of tiie 
annunciator, ami is shown slightly in pi-r- 
s)»octive. L> lejiiesents lignres upon theilial- 
]ilate, which aie intenilcd to be tiie same as 
the numbers of the rooms with which the an- 
nunciatoris connected. Letters are sometimes 
used instead of lignres. C are jKiintersoi- in- 
dicators, which are turned to the lignres nr 
letters to indicate the room from which a call 
is made. The dial-iilate .V is made a dark 
color, or jet-black. The ligures 1! are made 
tlie color of gold-leaf, and the indicators are 
made of light metal color, by preference; but 
I do not wish to limit my invention to making 
the figures gold color and the indicators light 
metal color, becjiuse the same contrast be- 
tween the dial, tigures, and indicators could 
be produced by making the indicators gold 
color and the figures liglit-iuetal color, and 



they would produce substantially the same 
a"pear,ince in connection with the black back- 
ground. 

I have not represente<l the difl'erent colors 

in the drawings, but have shown the dill'ercnt 

parts, .so that, when tal;en in connection with 

this descriiition, my in\ention will be limited 

j to the contrast of colors, substantially as 

I aliove siiecitied, my design, consisting of 

I the dark dial-plate and of the bright tigures 

and indic.tlors nr [loiiiters of different blight 

I colors, making the C(jntrast of colors, and 

presents a \ery attractive appearance. 
I Ha\ing thus described my invention, what 
\ I claim as new, and desire to secure by Let- 
I ters I'atent, is — 

j An ornamental design for an annunciator- 

; dial, consisting of the following features: a 

1 black backgidumljgilt lettersor tigures placed 

I thereon and arranged in rows across the dial, 

ami bright metal pointers corresi)onding in 

number and ariangement to said letters or 

figures, substantially as described.

an interval. Tiio interval at I) is for tlio 
purpose of takinj^ out one of the wires a.nd

may be jilaeed by the .side of the break. 

The breaks at H K are to aeeoinmodate fho

EXECDTOUS OF WILLIAM WHITING, DFCEASl':!), ASSIGNOUS TO EDWIN 
T. HOLMES. 

IMPROVEMENT IN ELECTRO-MAGNETIC HOUSE-ALARMS. 

Specification forming part of Loiters Patent No. 20,ir70, (iatf J July v!0, 1858 ; extended iicvon years; reissue 
No. 6,399, dated Augnst 17, 187.') ; application filcil July W. 187.'). 



To all whom it may concern: 

Bo it known that William Whitino, coun- 
sellor at law, lato of R«.\buiy, in the county ot 
Norfolk aud State of Massaclinsetts, did, iu hiss 
lifetime, make an invention of a new and use- 
ful Improveracnt in Electro-Magnetic Hou.se- 
Alarms, of wliicli the following is a full, clear, 
ftud exact description, reference being liiwl to 
the accompanying drawings making a part of 
this specifleatiou, in which — 

Figure 1 is a view of a portion of a dwelling- 
house with the said improved apparatus at- 
tached. Figs. 2 and 2" represent a vertical 
section tlirotigh the room, showing the indicat- 
ing aud alarm appHratus iJi elovafiou; Figs. 
3, 4, 6, 6, aud 7, deUiils to be referred to hero- 
after. 

Previous to the invention of said WiiiTiNri 
an apparatus had been eiuployed as a burglar- 
alarm in which u single electric circuit waa eiu- 
ployed in connectiou with the windows and 
doonj of a building, and so arranged that the 
opening of any one of them shoidd clo.se the 
circuit and sound an alarm. Such a|)paratns, 
■ however, furnished no indication of the where 
abouts of the wiudow or door so opeucd, and 
the proprietor was lell to search through the 
whole house for the iutruder, who was himself 
perhaps alarmed and enabled to csca|>e. Such 
aiiparutus, moreover, all'ordcd no means for 
the disconnection of any particular portion of 
the houso from tlie alaini iiistrunent indo 
IHjiidently of the otlicr poitious, so that it was 
imprtvcticable to disconnect a particular room 
Ov door froiii the alarm in.strument without dis- 
connecting tho entire iiouse. 

The objects atuiined by llie invention of said 
WniTlNG were tho i)roductioiiof a house-alarm 
which not only alarms tlu; pr<)i)Vietor or guard- 
ian of the houso on tlie intrnsion of a burglar, 
but at the same time indicates to him the part 
of tho house attiicked, so that his attention 
may bo immo<liutoly directed to tho particular 
room where an entry has be<Mi fttt«iiipt<!d or 
cfreclcd, and also the capiK'ity of disconntyU- 
ing one portion of the hou.se from tho alarm 
instriunent without <liHC<>une('ting the oth(^r 
I)ortions of tho lioiiso therefrom. 

Tho first of these objects was accoj.'jijli.shnd 



by the said WniTiNG by tho emplo\ i.ioiit of 
a series of electro-magnetic circuil.s (one for 
e.icli distinct room or portion of tho house to 
bo guarded) in connection with an indicator 
for indicating the portion of the house at- 
tiickc<l, and with an alarm apparatus, (for 
somuling tho alarm,) which is coraraoH to the 
several circuits of the series, the doors aud 
windows of the houso being so connected with 
the circiiiUs that the opening of any one of 
them shall closo or break the circuit with 
whicli it is connected, cause tho alarm to be 
sounded to all tho circuits of tho series, and 
indicate ni»on the indicator tho particular 
room us-sailed. 

The second of said objects was accomplished 
by said WiiiTiNQ by tho employment of a 
switch in each of tho magnetic circuits of the 
series which it was expedient to disconnect 
from the alarm instrument that was common 
to the whole series of circuits, so that the 
openings of the house controlled by said 
switch could b(» disconnecte<l from the com- 
mon alarm instrument without disconnectiug 
the other circuits of the series from that in- 
strument. 

In order that others skilled in tho art might 
understand and use the said invention, the 
said WuiTiNG represented the manner in 
wiiicli he carried the same into effect, as in 
tlio accompanying drawings, and described 
till' same in the following wonls: 

In the drawing. U is tho indicator, which is 
placed in ;iny convenioutpositiou in tho house 
to be |irotecto<l, (as in tho slooping-room of 
tlie proprietor.) It is hero shown attached to 
the wail of the room. It consists of a board, 
to which are secured tho electro inagneta 1, 2, 
;<, 4, .''), .iiid <), there being one magnet for each 
indicating-circiiit. The operation of all being 
similar but one will be described. I may here 
remark that each circuit of wires may i)rot«ct 
a single window or door, or a single room or 
entry. The latter plan is tho one hero repro- 
seiiletl. 

Near the indicator, in any convenient place, 
is sccnred n shelf, 0, which sti]iporLs tlie alarm 
apparatus. This consists of an oi(H:lro-raag- 
net, I", tiie armature of which, as tho magnet

(hiding: snbsUuR-c in a vibrrtd.ig arm con- 
Mcctcil will) the arm at 11 re, oiio of the wires of 
till) battery bcinp; in contact with the arm, 
ami the arm beinp; coiiiipcted with one end of 
the coil; bnt as the method of rinpiiif,' the 
bell forms no part of my |nt'sent invention it 
need not be more fully described. 

A battery, D, which ojicratcs the alarm a|i- 
pai-atus, and a battery, IC, which operates the 
iiuliciUor anil the indicjUinp; circuits, are 
jilaccd in any convenient and aeciirc situation. 
From 011(1 pole of the battery 1) tho wire n 
loads to the bi'.li-ma^nel I'"; and from this mat;- 
net another wire, n', leads i-n a piece of metal, 
i, secured to the board of the indicator 15. 'I'o 
tliis piece b is pivoted at c tin; armature f of 
the niaf,'nct 1 of the indicatiu. From the op- 
posite pole of the battery 1) tho wire d leads 
to a huok or staple at e, on the indicator- 
board, a^'ain.st which the armature/ si)riiips 
liaelc when the coil of the magnet 1 ceases to 
be charged. This armature is furnished with 
a small spring, i, which bears against, a pin in 
the board, for the |mrpose of throwing tlie ar- 
mature back. The wirc-s a, «', and d, and bat- 
tery D, constitute the licil-eirciiit, which is 
closed when the ai mature/ is in the position 
seen ill Fig. 2, and the bell is rung, as before 
explained. 

From one jiole of the battery E the wire /t i.s 
led to the magnet 1, and from the oi)posit<; end 
of the coil of this 111 agnot other wires and springs 
coiii|)lete the circuit, as will be hereafter c.\- 
plaincd, the wire '/ entering the opposite pole 
of tliis battery. These wires, with the springs 
and boxes to be described, and the battery IC, 
c^mstitutc tlie indieator-circiiit. AN'heii this 
circuit is clo.sed the magnet 1 is made, and its 
armature/ is drawn up to it. This breaks the 
bell circuit, as explained; but when tho cur- 
rent through the coil of the magnet I is broken 
the armature/ is thrown liack by its spring i 
into contact with the staple f, and the bell- 
circuit is completed. A small shield, k, on 
the end of the armature, covers a letter, A, 
attached to the tipper side of the Ixiard when- 
ever it is drawn up to its magnet, and dis- 
closes the letter whenever the armature is 
thrown bat;k by it« spring. Tims the bell is 
rung, and a letter imUcating the room is ex- 
posed to view each time the iiidi('ator-circuil 
is broken, 'i'iie manner in which this is broken 
or closed by the opening or shutting of a door 
or window, \\U\ now be expliiiiied. 

In the door IVame G, l''igs. 1 and 3, on the 
Hide to which the hinges aic att.;(che<l, is se- 
cured to a metal box, i/i, the back part of which 
may b(! open, a piece of nonconducting mate- 
rial, /, wjiich li.ses vertically troiii llie Ir.iiiH- (!. 
To this piece / is atUiched an Insnlat^'d pi(((' 
of luotal, n. A slot, «, is cut thioiigli the 



fiont plate of th(^ box tii of a sufllcionl Kir.e to 
ulldw a roller, ;), to project u short dlHtiinc.o 
beyond the Hue of the door-fi iiiiio. Thin roller 
;) has its axh' hung in a pipi^ to which in at- 
tached a ben t. spring, r. Tho jiiece n U plxoted 
lit t> to tho sides of the box in, mid Im ko ar- 
ranged with respect to the piece n that when 
the roller p projects through tbo idot o the 
spring r will not be in contact witli tho piece 
n, but rest against the up[K)r part of the piCNCo 
/, and when tho roller is pressed in by the 
closing of the door tho end of the 8)iriug v 
shall slide down into and in contact with the 
jiiecc 11, as seen in Fig. 4. lu Fig. 4 19 shown 
the manner in which rnising a window allows 
the roller;) io spring out through tho slot. (I 
may here state that a similar arrangcinpiit to 
tliiit just desciibeil for the door is jilaccd in 
the side of the frame of each window.) A 
groove, .1, is cut in tlie side of tho window- 
sash next to the box ;(i, of a suQicient width 
and depth to allow the roller p to B|)ring out 
thioiigli the slot o, as in Fig. 3 ; but as this 
groove does not extend (piito up to tho top of 
the sash, the upper [larl at (, which is not 
grooved, will press the roller back into the 
box (vhcnever the sash is shutdown, and when 
it is raised the roller will spring out into tho 
groove n anil allow the spring r to coine away 
from tlio iiiece n. A similar arrangement is 
attached to the upper sash, so that nhen it is 
imllcd dowu its roller p will spring out. EaoU 
of the above-described spring arranscraeuts is 
inolndcd in some one of the iudicator-circiiits 
in such a manner that whenever tlie springs r 
are iii contact with the pieces 71 the circuit 
will be closed, and when away from them will 
be broken. 

The following is the arrangement here 
adopted: 'J'he \\'\ro g from the battery E is at- 
tached to the box m at j; another wire, y, is 
atUiched to the insulated piece >i, and is led 
thence to the next box in in the circuit, (in the 
drawings, to the box in Iwg. -1 ;) and from the 
insulated inecc ;i of this window to the next 
box (if lliero are more of them) is led another 
wire, :. and so on tor each door or window of 
that room or circuit. From the last one tho 
wire :, Figs. -1 and L', is led to the magnet 1 of 
the indicator. 'I'hus the circuit which makes 
thisinagiict is from the battery )C through the 
lx)X m, pivot p, Rjiriug r, to insulated piece 11, 
when the sjiriug is down on it; thence through 
the wire 1/ to the next box, and so thiotigh all 
the boxes in the circuit; and from the piece 11 
of the last one through wiro ; to the magnet 
1; thence through wire A to the opposite pole 
of the. battery II. The wires u.sed arc coated 
or insulated in the. ordinary maniiei-. When 
UiuH arranged, if nil the doors and windows 
embraced in this circuit are shut, the circuit 
will Im.- closed, the magnet 1 will be made, and 
its .■iiniaturi^ /' will bo drawn up to it, w hen the

the piece n, nnd tlio indiciitor-circuit will lio 
broken, when the coil 1 will ccaso to he ii niiiR- 
net, its aruiftture will be thrown back b.v the 
spriupi, its indicfltinplettor will bo disclosed, 
and the bell-ciicuit trill bo ootnplcti'd lliroiigh 
the ftrnmtnro itself, causing the inftcnot F to 
ring the bell and give the alarm, which will 
be8onn<le<! eo long as the indicator-circuit re- 
mains broken and the battery IJ lasts. 

The systoui which I have described, in which 
a series of closed circuits is eni|)Ioyed in con- 
nection with an o|icn bell-circ.nit, is the one 
which I iirefer.; but this onler may bo re- 
versed, and a tciies of ()])en indicatiiig-ciicuits 
luay bo used in connection with an indicatoi- 
and an alarm apparatns; but this arrange- 
ment is by no means !fo safe as that above do- 
scribed. 

As before stated, eiich room or entry will 
|ja\e its own indicator circnit and magnet, 
and its indiaiting letter, labol, or nninbcr; 
but the same battery, IC, (if of swflicienL 
.strength,) may he embracc<l in all tliecircnit.s, 
or as many of tbem as it is found convenient, 
and the armature of all the indicator-uiagnet,s 
may be embraced in one bell-circuit by con- 
necting them with the wires a' and d. The 
wire a of the boll-circuit is furnished with a 
switch, e', and the wire h of the indicating- 
circuit with a similar switch, f. These are 
for the r.onvenience of the iiroprietor when 
bo wishes to oi>cii or clo.se either circnit; as, 
for iustJincc, when be rises iti the morning, 
and wishes to render the alarm inoi)crative, 
he turns the switch e", when the bcll-cireuit 
will reniaiu open, and the bell will not bo rung 
when the doors and windows are opened. 
Befcro ewitchiug on the boll-circuit at night 
be examines to see if all the indicating-cir- 
cuits ore closed. This ho will see at a glance, 
for If any door or window has been left open 
the armature of the magnet belonging to that 
circoit will not be drawn up,aud consequently 
the indicatiog-Ietter of that circuit will be ex- 
jwsed; and if the battery E has failed none 
of the magnets ou the board will bo made, 
and all the letters will l>e exposed, and if this 
battery should give out iu the night the boll 
would be ruiijt and give notice of it. When 
Le fludfttho iftdicatiug-circQita ere all in oi>era- 
tion he cloecs the switch e'laiid then, to inform 
himself If the battery D Is operative, ho 
tnrus the switch f, which breaks the circnit 
through the wire k, and thin causes the bell 
to ring if lt8 circuit is not interrupte<l. He 
may then close the switch and retire, knowing 
that the whole apparatus is "in working order. 
Aa it is deflirable to have it in the |)owcr of 
the inmates to oi)en a door or window without 
sounding the alarm, each room,or, if preferred, 
each door and window, may bo furnished with 
a switch similar to /*, placed in such a posi- 
tiou that by turning it the circuit will con- 
tlnoe made when the roller /j jprings out — for 
example, by attaching it to one side of the 
box m, and turning it in contact with the in- 
Bolated piece n, whoa the door or window 



is closeil again, iniK priviiio snilcli is Ininci. 
ofl', an<l llio pliice is protected as befiire. 

If desiriibli', two or iiioie bells imiy be in- 
clinled in tli<' same alarm-<:ir<'.iiit, (llie liallny 
I) being made strong enough,) and be ]ilaced 
in difl'iMcnt pans of the house, so that the in- 
mates may be simnlliineoii.-<ly infornieil of an 
iitlaRk, and llms rcndorcsicli oilier ]irompt as- 
Ri.st4incc. In this case a switch, as at <■', may 
be jdaccil near each bell, or they may all bo 
under the control of the proprietor, by means 
of switch z'. Ill lien of the arrangeimiit slmwn 
in I''ig. I, vvliciciii the closing ol the window 
piessi's in llie nillcr yi, and thereby closes tho 
(■.ircnil, anntlicr ariiingi lutiit h;is proved in 
practice still more clliciciit. The cavity « is 
made opposite to the roller ;/, and of a leiiKlh 
not inncli exceeding the diameter of the toller. 
When the window is closed, the roller springs 
out into \'. isea\ily. Instead of the uiie; l)e- 
iiig attiiclicd to the pi(!CC Ji, it is atlaclied to 
a similar insulated piece, c\ l'"ig. 5, on the up- 
])cr part of the iiieco /', so that when the \\iii- 
dow is rai.scd the roller ;) is pressed in and 
the spring r slides down out of contact with 
the piece (^, to which the wire is coHiiected, 
and thus the circnit is broken, and continues 
broken until the window is again ])laced in its 
original position. This insures not only the 
sounding of the aliirin, but the conlinn.ince 
of tho ringing of tho bell while the window 
is open, and remlers it still more dillicnll. for 
u burglar to meddlo with the window-spring 
without giving an alarm, •while in the arrange- 
ment represented in h'ig. 4, if the lower sash 
be raised entirely up, the roller ;> willbeagain 
pressed in and the circnit closed, and if, to 
prevent this, the groovo « be cut entirely to 
tliO bottom of the sash, and th(^ latter be raiseil 
entirely up, the roller might be reached by a 
stick or wedge and bo pre.-<sed in, and tliiis 
tho continuous ringing of tho bell be pre- 
vented. 

In place of the above-described spring ar- 
rangements, I sometimes use tho Ibllowing 
more. 8iini)lo one: Twy iiisulat<'d jiieces of 
meUil, d', Fig. G, similar to n, Fig. 'S, are se- 
cured to tho iniici Hurc of that part of the <vin- 
dow-frame with which tho sasii slides in con- 
tact whcnSt is raistsd or lowered. To each of 
these pieces rf' is connected one of the wires 
y and z. To the inner edge of tho"Sash, oppo- 
site those iiicco.1 when tho sash is closed, is se- 
cured n spring, ip, Fig. 6, in such a manner 
that when the window is cU)sed tb.' two iuins 
1 and 2 of the spring shall bo in contact with 
the inRulatO<l pirccM of metal d' ; but wlniiev er 
the window is raised tho spring ir will slide' 
out of contact with one or both of the pi('(tes 
d',and the circilit will bo broken and the alarm 
bo sounded, as before.

out of the way except wlieii its nso is re-

manently to one side of the window-frame a 
small spi ing-box, </', l"ig. 7, in which the wire

wire /', so that this wire may be drawn out 
of the box <i when rc()iiin'(l across the win-

tached to the other wire h' of the circuit on 
the op]iosite side, of the window.

langeil that when, by the breaking of either 
one III the indicating-circuit.s. Hie armalure/ 
is throw II back by its spring i, it shall let oil' 
a detent which will allow the jiower t'lnployetl 
to ring the bell to act. 

The ways of constructing alartii-bells which 
are. rung by mechanical power, and where 
tlu; ringing is permitted by the motion-giving 
machinery to a detent, are well known, and 
need not be. here ilescribeil ; but in my inveii 
tion the inolion of tli(^ detent is c.ailsi'd, not 
b\ the action of any jiart of the mechanism 
of the bell il.self, Imt by the movement of I he

recommend. 

Hereinbefore the letters of tbe indicator 
have been represented as exposed to view by 
the motion of the armature of the indicator- 
magnets; but it is obvious that other meth- 
ods of indicating may be employed, as, for

lirst, a series of olet:tro- magnetic circuits; 
seitond, an indicator to dcsigimto the rcsiicct-

ficatiou. . . , r "tT „(- 

Our invention relates to circuit-closers lor that 
classofburglar-alariusand signals whicliareoper- 
ated by a diflerence iu the flow of the current of a 
closed circuit; and the invention consists m a 
perm.inent magnet surrounded by one or mo^ 
ma-uet"iccoils, thereby fSrinmg an improved cir- 
cuit-closer. The invention likewise comprises a 
certain combination of an armature with a cir_ 
cuit-closer, wherebv the synchronous opening ol 
one circuit and closing of another i.s cllectcd by 
the action of said armature; and the invention 
fui-thermore includes a combination, with the per- 
manent magtiet, of a foil spring, whereby a more 
complete or perfect contact is obtained between 
said magnet and the point it makes and breaks 
circuit with. . , .. • <■

connection of the apparatus with cert-iiu batteries 

and an alarm-bell. 

Similar lettersof reference indicatecon-espond- 

iug parts througbout the several figures. 

D in the accompanying drawing is the perma- 
nent magnet surrounded or inclosed by one or 
more magnetic coils, C. F is an adjusting-screw 
arranged so that when the coils C are uot.charged 
it will always be in metallic connection with the 
magnet D by the impinging or embedding of it, 
as produced by the deflection of the magnet 
against or within a fine foil springs, one end of 
which is soldered to the magnet. Said spring is 
u.sed to insure electrical contact with the .screw 
F and, by making said spring of thin foil, this is 
more etVecluallv and certainly acconiidished than 
when mere contact of the spring and end ot the 
screw is relied upon, as dust or dirt getting upon 
the end of the screw would arrest or interfere with 



the passage of the current, whereas a spring made 
of thin foil allows of the point of the screw em- 
bedding itself therein ; consequently the louling 
of the end of the screw would be of but little or 
no importance. E is a similar .^^crew, but so ar- 
ran"-ed and adjusted that when the usual current 
is iiassing through the coils C the magnet D will 
almost, but not quite, touch it. H represents a 
pair of' electromagnets, provided with an arma- 
ture, 1, which is notched at its one end so as to 
engage with a hook upon the ann of a drop, K, 
pivoted, as at b, and so arranged and constructed 
that when released by the armature I it will fall 
upon and move downward an upriglit arm of a 
circuit-breaker, L, and cause the latter to rest 
upon a pin, c. Said circiiJO^rcakerJLnsjMvo^t 
i'lTtCTmc^diStelv^nti'lengtirTSniiat when its one 
end is in contoctwith the pin c its other endwiU 
be thrown up and made to break contact with' a 
pin or stop, d. The circuit-breaker L has its con- 
tact \vith thepiJi or stop c broken and its contact 
with the pin d e.stabUshed by a .spring, e, when 
relievedfi-om theweight of thedrop K. Thepivot 
of L is connected, by a wire, i, with screw-cups 4 
and 5 and connection continued from thence, by 
the wire i, to one pole at the battery B; and Oie 
pin or stop d is connected, by a wire, k, to the 
wire of the eleetro-magnets H, and connection 
continued from thence, by a wire, vi, to the ad- 
justing-screws E and F. The pin c is connected, 
by a wire, !, to a signal or alann-bell, W, and from 
thence by said wire, /. through a screw-cup, b, to 
the other pole of the battery B. A is a batteij, 
having one of its poles connected, by a wire, o, to 
the place or structiure to be guarded or signal to 
be made, from whence said wire returns to a 
screw-cup, 1, and, passing through the ^^^^'^ 
coils C, emerges at a screw-cup, 2, andfromfbence 
to the other pole of the batter;j;^^.;^J3erma- 
nent magnet D is in conuectioli. by^ wire, n, 
through a screw-cup, 3, with the battery B. 

The operation of the invention as applied to a 
burclar-alarm, which is the purpose here selected 
for illustration, is as follows: When the points or 
places to be guarded are closed and secured a 
current will flow from the battery A through the 
wire or circuit o and magnetic coils G. /'"S will 
cau.se the magnet D to approach basely to, but 
not (luite touch, the adjusting-screw E, at tt^*- same 
time breaking contact between the magnet D and 
screw F. The drop K is set to engage with the 



(244) 



120,744 



armature I. This being the couditiou, tlie circuits 
closer is theu in proper position for ])rotccting the 
exposed points or places, and the magnet D, as in 
Fig. 3, touches neither of the adjusting-screws E 
and F. If any attempt be made to enter the point 
or place guarded by means wliich cause the flow 
of the current through the coils C to be increased, 
then the magnet D will instantaneously deflect to 
a contact with the adjusting-screw E. This will 
close the circuit i of the battery B, and the cur- 
rent, passing through magnet H and^attracting 
the armature I, will release the drop K, which, 
in falling upon the upright arm of the cu'cuit- 
breaker L, will break contact between the latter 
and the pin d and establish contact between said 
circuit-breaker and the pin or stop c, thereby com- 
pleting the circuit I through the alarm W and 
the batt-ery B and sounding a continuous alarm. 
If any attempt be made to enter the point or place 
guarded by means which cause the flow of the 
current through the circuit o to be broken or di- 
minished, the magnet D would fall and establish 
contact with the adjusting screw F,and thus close 
the circuit t m of the battery B and sound the 
alarm, as before. 

While we prefer to use two batteries, A and B, 
as described, one batterj' might be made to an- 
swer without changing the character or principle 
of the iuventiou. Neither do we confine our- 
selves to making the magnet D of itself close the 



circuit of the battei7B,a8 it is obvious that said 
mag;aot niight be made to cany or actuate an in- 
dependent circuit-closer with substantially the 
same effect; nor do we restrict ourselves to the 
use of the .adjusting-screws E and F. as a like 
contact with the magnet D can be maae in'viiri- 
ous ways or by other means without changing 
the invention. 

Instead of the alarm-bell, too, any other audi- 
ble or visible signal might be used. 

What we here claim, and desired to secure by 
Letters Patent, is — 

1. The circuit-closer, consisting of the permar 
neut magnet D, surrounded or inclosed by the 
magnetic coil or coUs C C, charged by a primary 
circuit, and operating substantially as described, 
for the purpose set forth. 

2. The combinjTtion of the armature I with the 
circuit-closer L, whereby the synchronous open- 
hig of one circuit and the closing of another by 
the aetion of said armature is efiected, substan- 
tially as specified. 

3. The combination of the foil spring s with the 
magnet D, essentially as described.

cJ^emS/eJf, /^J. 



The Subscribers respectfully ask your attention to this very important invention. Daily experience 
renews our warning that no Locks or Bolts are sufficient to keep Robbers out, and also, that when they 
have entered the house they will often add murder to their crime rather than forsake their plunder. But, 
an alarm given before they enter is sure to drive them away. Of this we have abundant proof in the testi- 
mony of those who have been provided with our protection. 

Our Mr. Guest, during ten years of practical application and study, has brouglit to a perfect system the 
arrangement of an Electro-Magnetic Alarm, and we confidently offer it as free from the annoy- 
ing defects of the older efforts, and a sure protection against Burglary, and the carelessness of 
servants. 
It can be put in your house at small expense, and without any injury to the building, or any material dis- 
turbance of carpets or furniture. You then have a simple and compact apparatus, ornamental in 
appearance, and easily understood, placed with its Bell and "Indicator" in any room you may select, 
and the conducting wires are attached to the windows and doors requiring them, without being 
exposed to sight at any point of their route. When the attachment is set for the night (which is 
done by the movement of a small switch on the Bell in your room), should you wish to know if any 
window or door has been accidentally left open, the movement of a Knob on the instrument will at 
once answer your enquiry. You can then retire to bed with a perfect assurance that your Bell will 
be rung loudly if any attempt is made to enter your house. 
In the morning, a reverse movement by your thumb and finger will detach the connection ; or, if you pre- 
fer not to have your sleep disturbed by the servants opening the house, you can have a "Clock 
Circuit Breaker," which can be set so that the Bell will not ring after a designated hour. 
The wires can be carried into Stables or other detached buildings, and controlled by the same instrument 

in your bedroom. 
Our Annunciator, with a needle revolving upon a dial, which is marked to correspond with the rooms, 
is a beautiful improvement upon the old system oi pull bells, whose wires require constant repairs, 
from their tendency to break or stretch. 
In addition to this protection against Burglars, and in connection with it, can be attached our patented 
Fire Alarm Apparatus. A small glass bulb, of about an inch square in size, placed in each room, 
will ring your Alarm Hell when the heat in either room becomes inordinate, and your "Indicator 
will immediately designate the locality where the danger exists. 
We have no controversy with any fair competitor, nor any disposition to bandy words with others. We 
claim to offer a superior article. A cleanly, regular, and enduring Battery ; a Bell Apparatus 
of simple and automatic construction, that requires no "expert" to regulate, and invariably receives 
commendation when inspected ; and newly-invented and patented Springs that do not break and are 
certain of action. We pay great attention also to beauty of form and finish in our instruments, so 
that they are an ornament in any house. 
We only ask an examination and comparison of relative merits. Please call at our office, and see the 
beauty and simplicity of the machinery and its operation.

Improved Electro-Magnetic Burglar and Fire Alarm 

July 14, 1868

United States Patent Office. 

JOHN H. GXJE8T, OF BROOKLYN, NEW YORK. 
IMPROVED ELECTRO-MAGNETIC BURGLAR AND FIRE ALARM. 

Specification fonniDg part of LetUr. P»t«nt No. 79,973, .Iftted July 14, 1868. 



To all ic)iom it may concern: 

Be it kuowii tbat I, John H. Guest, of 
Brooklyn, in tlio county of Kings and State of 
New York, liave invented and made a certain 
new and useful Improvement in Fire and Bur- 
glar Alarms; and I do bereby declare the fol- 
lowing to be a full, clear, and exact description 
of the said invention, reference being had to 
ihe annexed drawings, making part of thiH 
SiHicification, -wberein— 

Figure 1 is au elevation of the magnets and 
bell. Fig. 2 is a plan of tbe same. Fig. 3 is 
a section of the thermal circuit-closer. Fig. 4 
is an elevation, and Fig. 5 a section, of the 
designating auddisconnectingapparatas. Fig. 
6 is a section of the circuit-closer that is con- 
nected with a window, to close the circuit when 
naid window is opened. Fig. 7 is a section of 
the circuit-closer that is employed with a door i 
or other swinging article. 

Similar marks of reference denote the same 
parts. 

This apparatus is arranged upon the gener- 
ally-known plan of giving an alarm by a bell 
whenever thercircuit of a galvanic battery is 
closed by the movement of any device that 
should remain stationary, thus giving an alarm 
and indicating that some portion of the appa- 
ratus is not iu a normal condition. 

I will first describe my alarm-bell, which 
consists in two magnets, a and ft, with two 
armatures, c and d, on one lever, e, that is hung 
to oscillate, and is connected with the hammer 
/that strikes the bell g. h and t are springs 
to the adjustable circuit-closers k and L 

By reference to the lines in Fig. 2, indicating 
the wires of the electrical circuit, it will be seen 
that when the electricity passes through the 
helix of the magnet a the attraction of its ar- 
mature will separate ♦ and I and break the 
circuit to itself, and at the same time close h 
and Ic, and cause the magnet b to attract its 
armature d, and thereby reverse the circuits, 
and this is done with the utmost rapidity, 
causing the hammer to strike the bell, and that 
without depending on springs to produce the 
reverse movement, as heretofore. 

The lever e is suspended either by a spring, 
&, as shown iu Fig. 1, from the screw d', by 
which the position of thearmatures is adjusted, 
or said lever e may be centered by screws a' 
iu a yoke, I', tbat is adjusted vertically by the 
screw d', and the centering-screws o', passing 



through slots in the frame c*, prevent lateral 
motion, so that the armatures are free to vi- 
brate, but cannot easily become displaced. 
,Fig. » represents this variation in the mode of 
hanging the armatures. 

The switch c*, when standing between the 
studs 'J and 3, causes the whole apparatus to 
be inoiierative. When upon the stud 2 tbe 
apparatus is in position for use when either of 
tbe alarm circuit -closers are brought into 
action, and by turning the switch to the stud 
3 the bell may be rung to test the battery, to 
see if it is iu order, without actually examin- 
iug the pr""*^. 

The thermal circuit-closer. Fig. 3, consists 
of ai\ air-tight box, t», tbat is formed with au 
expanding liea<l,4, of thin metal, corrugated 
concentrically, and near tbe center of this is 
hinged the circuit^closer m', that, iu a normal 
condition, is sustained by tbe book 5, but when 
the air in tbe box m expands by tbe tempera- 
ture of the apartment in which it is applied, 
rising beyond a certain i>oint, the head 4, being 
pressed outwardly iu its center, causes, the 
closer m' to unlatch, and it drops upon the 
arm G, to which one wire of the circuit is con- 
nected, while the other is connected to the box 
m, thus closing the circuit and ringing the 
bell. 

In Fig. 3 I have shown tbe box m and arm 
m' movable, so that they may be adjusted by a 
screw, 7, to any desired i)oint, so that the alarm 
will be given at a definite temperature, and 8 
is a dial upon which figures may be marked 
to indicate at a fixed pointer, 9, the degree of 
heat at which the apparatus will become oper- 

'^t'ive. „ ,. , o 

In Fig. 8 I have shown the screw 7, dial 8, 
and pointer 9, as applied to the hook 5. to ad- 
just tbat instead of tbe box »i. 

The circuit-closer, which becomes a temper- 
ature or fire alarm, is to be located in any de- 
sired part of a building. It is preferable that 
the same bo attached to the ceiling, as being 
iu a position to be most likely to operate by 
changes of temperature. 

The circuit closer for a window. Fig. 6, is 
made of a hanging pendulum, n, upon a fbl- 
crum, 10, to which one wire of the battery is 
applied. The upper end, 11, of this pendulum 
is a spring, and when the window-sash o is m 
its normal or closed position the pendulum n 
hangs freely in a notch in the side of the sash } 



(253)

bat as Boon as tlic snsli is raised the pendu- 
lam n is moved, and tbe spriug II comes into 
ooutAct with tbe block 12, to wliicb the otiier 
wire of tbe batterj- is connected, and thereby 
tbe circuit is closed and the alarm given. 

Tbe device for acting with a door or other 
swinging article, Fig. 7, consists in a plate, p, 
to which the spring 13 is attached, and also one 
the wires of the battery. 

14 is a second spring insulated from the 
plate p, but, for convenience, connected there- 
upon, and to this the other battery-wire is 
connected. 

The door w, acting against the pusher q upon 
the spring 14, separates the springs 14 and 13 
whenHhe door is closed ; but when it is opened 
the two springs come together and close the 
cireait. 

The designating and disconnecting appara- 
tus (j»liown inFiga. 4 and 5) consists in a plate, 
r, to which one of the battery-wires is con- 
nected. Through this plate there are as many 
holes as there are points to be designated by 
the connections of the battery, such us " fire," 
"window," "door," or other sub-designations, 
and in each of these holes is placed a screw- 
stud, a, that is insulated fr<An said plate by 
being smaller than the hole, so as not to tonch 
it, and said stud receives it« snpportfrom the 
wooden or other non-conducting base of the 
plate r. 

A wire from thedifierent points to be desig- 
nated leads to the different studs «, and on 
each stud is a nut (, and the button-head of 
the stud may be appropriately eugraved or 
marked with the name required. 

Ail the nnts t should l>e kept screwed upon 
theplAter. Ifthe alarm-bell rings, theattcud- 
nnt unscrews first oue nut, t, and then another, 
until he arrives at the particular circuit that 



has l>©en closed and is operative, which ht 
knows by the separatiou of t and r, Stopping 
tbe bell by breaking that particular circuit, 
and thus it is known what partof the premises 
requires attention. 

In place of a metal nir-box tbe corrugated 
disk forming the circuit-closer might be set in 
a woodeu rim, and act by its expansion as tbe 
thermal circuit-closer. 

What I claim, and desire to secure by Let- 
ters Patent, is — 

1. A pairofmagnetsand armatures arranged 
niid acting in tbe manner 8)>ecifled, in combi- 
nation with a hammer and bell, tbe former 
being attacbe<l to the lever of the armature, 
for tho purposes, and as set fortii. 

2. An expansive corrugated <lisk andhinged 
arm forming a tiicrmal circuit-closer, substan- 
tially as set forth. 

3. The adjusting- screw 7, in combination 
with tbe thermal circuit-closer, as and for the 
purposes set forth. 

4. The ]>endulum and s[)ring, in combina- 
tion Willi tho circuit-wirc.H and notched sash 
or slide to close the circuit, as 8i>ecifle<l. 

5. Tbe two springs 13 14, connected with tbe 
circuit-wiri«,, in combination with the-pnsher 
g, for the puqwses, and as set forth. 

G. The plate r, screw-studs », and nuts <, con- 
structed substantially as specified, in combi- 
nation with the circuit-wires, to form a desig- 
nating or disconnecting apparatus in a fire or 
burglar alarm, substantiaily as net forth.

IVaine for closin;; the ciicnit as mxiii n.s tlic kisIi 
is elcNaled. 

A in the «lr.iwiii;r i-ci>rc.senls the bell of the 
Iim';;lar-alariii. I! is the clajiper of the same, 
connected with the vilmiliii}; armature (!, which 
is pi\oted opposite the elect i'o-liia;,'liets 1). J''roni 
the anna I nil* projects a hori/ontal spring; or arm, 
fi. Ii is a flat spriii','-, secured to a fninie or hold-

aliove the arm <i. J>nriu;; the vihralion of tiic 
armatnre the spiiiif,' w will strike the sprin;,'/' 
with ^jreatcror lesser intensity, accordin;: to the 
height of the latter. The stroUes of thearma- 
tnri! are thereby controlled, the clapper bein^ 
thrown with >;reatcr or lesser violeiico ajrainst 
Iho btrll. The ahiiin iiistrnmcnt is, by wires _/' 
and </, connecteil with the battery and with two 
metal jilates, E and 1'". The jilati* K is sunk 
into tli<! top of the window-frnnic G, and is, at 
A, iiiHiilateil I'lxMu the plate F held ab<)\o it. II 
is a metal beam or bar, ]iivoted at / to metal 
luf,'H that project from the plati! E. One end ol' 
the Ileum II is wei;;liteil by a ball, _;, or eipiiv- 
alent means. 'J'he other end is, by a cord or 
chiiiii, I, eonnected with the lower wlndowsash 
•I. 'J'liis chain, when the sash is down, holds 
the beniit II balanced, iso that neither end is in 
coiiUict with llio iilafo F iibovo. Wlioii, how- 



ever, the chain is )inlled by inoddlinK with the 
windinvpancs oi' direct, contact, it draws one. end 
of the beam down and swin^^s the wei;,'litcd end

i-liain is slackened by ele\atin;,' the lower sash 
or cut, t lie \\ci;,'lilcd end of tliC! beam II descends 
and carries the other end in contact with the 
plale !■". In either case, therefore, melallie i-oii-

.M, which are secured to the. inner ed;:e of the 
window-fraine, belwcen the Kaino and the e<l;,'e 
of the u iiidiiw-sasli. The iipiier spriii;,'-plate Ii 
sprin;;s into a notch, /, of the window-.s;isli when 
the latter is down or clo.sed; but when the K;niie 
is mi.scil it <-rowds the plale L a;;ainst ii spring, 
N','\vhi<-li is in contact with M, and eslablislie.s 
thereby metallic connection iM-tweeii the \viiv«/ 
and //. 

A metal jilate, )//, ChIII be secnrwl to thcodgo 
of the sash to make <liroct eoiiiiection iK-tweeii 
the plate Land M. 

The plate Ii may be sus|ieuded from its fast- 
eiic<l end, and the jilale .M project upwanl, as 
shown, at the left-hand side of the dniwiii;:, or 
both be siispeiided, as on the. ri;;ht-liand siih*. 
In the lattci' case the sprin;,' X and jilate in may 
both be dispiMised with. \\'lien the .sash is rai.sed 
clear of the plales I, ,M, to be no Ion;;ei- in <'on- 
lacl. with the same, the cir<'.uit is closed by the 
spriii;r of Ihe plates, wlilcli tlirow8 tliein in con-

The McWilliamses 
and the Burglar Alarm 



The conversation drifted smoothly and pleasantly along from weather 
to crops, from crops to literature, from literature to scandal, from scan- 
dal to religion; then took a random jump, and landed on the subject 
of burglar alarms. And now for the first time Mr. McWiUiams showed 
feeling. Whenever I perceive this sign on this man's dial, I compre- 
hend it, and lapse into silence, and give him opportunity to unload his 
heart. Said he, with but ill-controUed emotion: 

I do not go one single cent on burglar alarms, Mr. Twain-not a single 
cent-and I will tell you why. When we were finishing our house, we 
found we had a Uttle cash left over, on account of the plumber not 
knowing it. I was for enhghtening the heathen with it, for I was al- 
ways unaccountably down on the heathen somehow; but Mrs. McWil- 
Uams said no, let's have a burglar alarm. I agreed to this compromise. 
1 will explain that whenever I want a thing, and Mrs. McWilhams wants 
another thing, and we decide upon the thing that Mrs. McWilliams 
wants-as we always do— she calls that a compromise. Very well: the 
man came up from New York and put in the alarm, and charged three 
hundred and twenty-five dollars for it, and said we could sleep with- 
out uneasiness now. So we did for awhile— say a month. Then one night 
we smelled smoke, and I was advised to get up and see what the matter 
was. I lit a candle, and started toward the stairs, and met a burglar 
coming out of a room with a basket of tinware, which he had mistaken 
(or solid sUver in the dark. He was smoking a pipe. I said, "My friend, 
we do not allow smoking in this room." He said he was a stranger, 
and could not be expected to know the rules of the house: said he 
bad been in many houses just as good as this one, and it had never 
been objected to before. He added that as far as his experience went, 
rich rules had never been considered to apply to burglars, anyway. 

I said: "Smoke along, then, if it is the custom, though 1 tliink that 



(269) 



tlie cx>ncedmg of a privilege to a burglar which is denied to u bishop 
is a conspicuous sign of the looseness of the times. But waiving all that, 
what business have you to be entering this house in this furtive and 
clandestine way, without ringing the burglar alarm?" 

He looked confused and ashamed, and said, with embarrassment; "I 
beg a thousand pardons. I did not know you had a burglar alarm, else 
I would have rung it I beg you will not mention it where my parents 
may hear of it, for they are old and feeble, and such a seemingly wanton 
breach of the hallowed conventionalities of our Christian civilization 
might all too rudely sunder the frail bridge which hangs darkling be- 
tween the pale and evanescent present and the solemn great deeps of 
the eternities. May 1 trouble you for a match?" 

I said: "Your sentiments do you honor, but if you will allow me to 
say it, metaphor is not your best hold. Spare your thigh; this kind light 
only on the box, and seldom there, in fact, if my experience may b« 
trusted. But to return to business: how did you get in here?" 

"Through a second-story window." 

It was even so. I redeemed the tinware at pawoibroker's rates, less 
cost of advertising, bade the burglar good-night, closed the window 
after him, and retired to headquarters to report Next morning we sent 
for the burglar-alarm man, and he came up and explained that the 
reason the alarm did not "go oflT was that no part of the house but the 
first floor was attached to the alarm. This was simply idiotic; one might 
as well have no armor on at all in battle as to have It only on his legj. 
The expert now put the whole second story on the alarm, charged 
three hundred dollars for it and went his way. By and by, one night, 
I found a burglar in the third story, about to start down a ladder with 
a lot of miscellaneous property. My first impulse was to crack his head 
with a billiard cue; but my second was to refrain from this attention, 
because he was between me and the cue rack. The second impulse 
was plainly the soundest so I refrained, and proceeded to compromisa. 
1 redeemed the property at former rates, after deducting ten per cent 
for use of ladder, it being my ladder, and next day we sent down 
for the expert once more, and had the third story attached to the alarm, 
for three hundred dollars. 

By this tLme the "annunciator" had grown to formidable dimensions. 
It had forty-seven tags on it marked with the names of the various 
rooms and chimneys, and it occupied the space of an ordinary ward- 
robe. The gong was the size of a wash-bowl, and was placed above the 
head of our bed. There was a wire from the house to the coachman 'i 
quarters in the stable, and a itoble gong alongside his pillow. 



(270) 



We should have been comfortable now but for one defect. Every 
Qiorning at five the cook opened the Idtchen door, in the way of busi- 
ness, and rip went tliat gongi The first time this happened I thought the 
last day was come sure. I didn't think it in bed— no, but out of it— for 
tlie first effect of that frightful gong is to hurl you across tlie house, 
and slam you against the wall, and then curl you up, and squirm you 
like a spider on a stove hd, till somebody shuts the kitchen door. In 
solid fact, there is no clamor that is even remotely comparable to the 
dire clamor which that gong makes. Well, this catastrophe happened 
every morning regularly at five o'clock, and lost us three hours sleep; 
(or, mind you, when that thing wakes you, it doesn't merely wake you 
Id spots; it wakes you all over, conscience and all, and you are good 
for eighteen hours of wide-awakeness subsequently— eighteen hours of 
the ver>' most inconceivable wide-awakeness that you ever experienced 
la your life. A stranger died on our hands one time, and we vacated 
and left him in our room overnight. Did that stranger wait for tlie gen- 
eral judgment'P No, sir; he got up at five die next morning in tfie most 
prompt and unostentatious way. 1 knew he would; I knew it mighty well. 
He collected his life-insurance, and hved happy ever after, for there 
was plenty of proof as to the perfect squareness of his death. 

Well, we were gradually fading toward a better land, on account 
uf the daily loss of sleep; so we finally had the expert up again, and he 
ran a wire to the outside of the door, and placed a switch there, whereby 
Thomas, the butler, always made one httle mistake— he switched the 
alarm off at night when he went to bed, and switched it on again at day- 
break in the morning, just in time for the cook to open the kitchen 
door, and enable that gong to slam us across the house, sometimes 
breaking a window with one or the other of us. At the end of a week 
we recognized that this switch business was a delusion and a snare. We 
also discovered that a band of burglars had been lodging in tlie house 
Ibe whole time— not exactly to steal, for there wasn't much left now, 
but to hide from the poUce, for they were hot pressed, and they 
shrewdly judged that the detectives would never tliink of a tribe of 
burglars taking sanctuary in a house notoriously protected by the most 
Imposing and elaborate burglar alarm in America. 

Sent down for the expert again, and this time he struck a most daz- 
iling idea-he fixed the thing so that opening the kitchen door would 
take off the alarm. It was a noble idea, and he charged accordingly. 
But you aheady foresee the result. I switched on the alarm every night 
at bed-time, no longer trusting on Thomas's frail memory; and as soon 



(271) 



as the lights were out the burglars walked In at the Idtchen door, thus 
tiidng the alarm off without waiting for the cook to do it in the morning. 
You see how aggravatingly we were situated. For months we couldn't 
have any company. Not a spare bed in the house; all occupied by 
burglars. 

Finally, I got up a cure of my own. The expert answered the call, 
and ran another ground wire to the stable, and established a switch 
there, so that the coachman could put on and take oS the alarm. That 
worked first rate, and a season of peace ensued, during which we got 
to inviting company once more and enjoying Ufe. 

But by and by the irrepressible alarm invented a new kink. One win- 
ter's night we were flung out of l)ed by the sudden music of that awful 
gong, and when we hobbled to the annunciator, turned up the gas, and 
saw the word "Nursery" exposed, Mrs. McWiUiams fainted dead away, 
and I came precious near doing the same thing myself. I seized my 
shotgun, and stood timing the coaclunan wliilst that appalhng buzzing 
went on. I knew that his gong had flung him out, too, and that he 
would be along witli liis gun as soon as he could jump into his clothes. 
When 1 judged tfiat the time was ripe, I crept to the room next the 
nursery, glanced tfuough the window, and saw the dim outhne of the 
coachman in the yard below, standing at present-arms and waiting for a 
chance. Then I hopped into the nursery and fired, and in the same 
instant the coachman fired at the red flash of my gun. Both of us were 
successful; I crippled a nurse, and he shot off all my back hair. We 
turned up the gas, and telephoned for a surgeon. There was not a sign 
of a burglar, and no wmdow had been raised. One glass was absent, 
but that was where the coachman's charge had come tluough. Here 
was a fine mystery-a burglar alarm "going ofT at midnight of its own 
accord, and not a burglar in the neighborhood! 

The expert answered the usual call, and explained that it was a 
"False alarm." Said it was easily fixed. So he overhauled tlie nursery 
window, charged a remunerative figure for it, and departed. 

What we suffered from false alarms for the next three years no st>'lo- 
graphic pen can describe. During the next three months I always flew 
with my gun to the room indicated, and the coachman always sallied 
fortli with his battery to support me. But there was never anything to 
shoot at— windows all tight and secure. We always sent down for the 
expert next day, and he fixed those particular windows so they would 
keep quiet a week or so, and always remembered to send us a bill 
about like this.

At length a perfectly natural thing came about— after we had an- 
swered three or four hundred false alarms— to wit, we stopped answer- 
ing them. Yes, I simply rose up calmly, when slammed across the house 
by the alarm, calmly inspected the annunciator, took note of the room 
Indicated, and then calmly disconnected that room from the alarm, and 
went back to bed as if nothing had happened. Moreover, I left that room 
off permanendy, and did not send for the expert. Well, it goes without 
saying that in the course of time all the rooms were taken off, and 
the entire machine was out of service. 

It was at this unprotected time that the heaviest calamity of all hap- 
pened. The burglars walked in one night and carried off the burglar 
alarml yes, sir, every hide and hair of it: ripped it out, tooth and nail; 
springs, bells, gongs, battery, and all; they took a hundred and fifty 
miles of copper wire; they just cleaned her out, bag and baggage, and 
never left us a vestige of her to swear at— swear by, I mean. 

We had a time of it to get her back; but we accomplished it finally, 
for money. The alarm firm said that what we needed now was to have 
her put in right— with their new patent springs in the windows to make 
false alarms impossible, and their new patent clock attached to take off 
and put on the alarm morning and night without human assistance. 
That seemed a good scheme. They promised to have the whole thing 
finished in ten days. They began work, and we left for the summer. 
They worked a couple of days; then they left for the summer. After 
which the burglars moved in, and began their summer vacation. When 
we retujrned in the fall, the house was as empty as a beer closet in 



(273) 



premises where painters have been at work. We refurnished, and then 
sent down to hurry up the expert He came up and finished the job, 
and said: "Now this clock is set to put on the alarm every night at lo, 
and take it off every morning at 5:45. All you've got to do is to wind 
her up every week, and then leave her alone— she will take care of the 
alarm herself." 

After that we had a most tranquil season during three months. The 
bill was prodigious, of course, and I had said I would not pay it until 
the new machinery had proved itself to be flawless. The time stipulated 
was three months. So I paid the bill, and the very next day the alarm 
went to bu22ing like ten thousand bee swarms at ten o'clock in the 
morning. I turned the hands around twelve hours, according to instruc- 
tions, and this took off the alarm; but tiiere was another hitch at night, 
and I had to set her ahead twelve hours once more to get her to put 
the alarm on again. That sort of nonsense went on a week or two, then 
the expert came up and put in a new clock. He came up every tliree 
months during the next three years, and put in a new clock. But it was 
always a failure. His clocks all had the same perverse defect: they 
would put the alarm on in the daytime, and they would not put it on at 
night; and if you forced it on yourself, they uxntld take it off again 
the minute your back was turned. 

Now there is the history of that burglar alarm— everything just as It 
hapjjened; nothing extenuated, and naught set down In mahce. Yes, 
sir,— and when I had slept nine years with burglars, and maintained an 
expensive burglar alarm the whole time, for their protection, not mine, 
and at my sole cost— for not a d d cent could I ever get them to con- 
tribute—I just said to Mrs. McWilliams that I had had enough of that 
land of pie; so with her full consent I took the whole thing out and 
traded it off for a dog, and shot the dog. I don't know what you think 
about it Mr. Twain; but / think those things are made solely in the 
interest of the burglars. Yes, sir, a burglar alarm combines in its person 
all that is objectionable about a fire, a riot and a harem, and at the 
same time had none of the compensating advantages, of one sort or 
another, that customarily belong with that combination. Good-by: I get 
off here.

Our Rival The Rascal (1897; reprint, Montclair,

survey of nineteenth-century burglary techniques and 
history, the authors describe the modi s- operandi of 
the several classes of robbers who practice the 
"art" of robbery. The house-breaker or sneak thieves 
generally worked during daylight or early evening 
hours. Often, they were young boys who did not 
attempt complex jobs. They would ring the doorbell 
on some pretext and if they discovered the house 
unoccupied, they would break in to ransack drawers 
and closets looking for small objects such as jewel- 
ry, silver, clothing or money. The more sophisti- 
cated and dangerous "second story climber" gained 
access through the second floor of a house. Although 
their take was similar, these "climbers" usually 
worked in pairs and would have surveyed the premises 
in advance to be certain of routines and to verify 
value. "Far above all these house-breakers and 
sneak thieves, in his own esteem and in point of 
offense, is the night raider or professional burglar 
who makes the dwelling house his mark." Generally 
working as an armed pair - their approach is made in 
dead of night to a previously marked house. ( Our

(25) Although no other patents are directly 
attributed to Edwin Holmes does not mean that he did 
not control other technology. Patents were assigned 
or sold on a regular basis. It is assumed that this 
is how Holmes received his rights to other improve- 
ments in his system. Only when the assignment took 
place at the time of patent application would the 
new owner's name be registered in the index along 
with the name of the inventor. Otherwise, the only 
way to establish transfer of ownership is to use the 
Pat en t Ass i gnment Digest (National Archives, Wash- 
ington, D.C.). First, it is necessary to select the 
patents to be checked in the assignment digest. Few 
patent titles indicate whether they are for electri- 
cally or mechanically based systems. Therefore, The 
Index of Patents Relating to Electricity Prior to 
18 81 is an essential tool. Patents which fell into 
the most promising electrical subclasses [burglar 
alarms, annunciators; bells; circuit closer; clocks 
and meters] were compared with those 
the subject matter index as being 
related. When a patent appeared on 
became a candidate for examination in 
digest. For this study, a list of 
three hundred patents was generated,

both lists it

app r ox ima t e 1 y 

Because the 

checking these 



patents for an assignment is a lengthy process. 
First, the index to the assignment digest is con- 
sulted to determine volume and page number within 
the digest where a patentee with a given name is 
registered. Of course, the more common the name, 
the greater the number of citations that will be 
produced - all of which must be checked to determine 
if they relate to the patent in question. The 
corresponding volume of the assignment digest is 
consulted to see to whom the patent was assigned and 
if it is in fact the patent in question. Unfortu- 
nately, this painstaking procedure failed to iden- 
tify additional Holmes controlled patents. This 
process, because of its complexity, is full of 
potential problems, an incorrect spelling anywhere 
in the process can result in a dead end. Even without er- 



278 



rors or omissions in procedure, failure to register 
a patent assignment, and errors within the digest 
itself cannot be overcome. For example, it is cer- 
tain that Holmes received the Pope assignment, yet 
this transfer is not recorded in the assignment 
digest .

(33) Moses Gerrish Farmer was born in New Hampshire 
and educated at the Andover, Massachusetts preparatory 
school. He attended, but due to ill health, did not com- 



279 



plete his studies at Dartmouth College. Farmer 
devised a machine to print paper window shades and 
thus began his career as an inventor. In 1845 he 
became interested in electricity. After learning 
telegraphy he became an operator and later took 
charge and was responsible for opening offices on 
the line between Boston and Newburyport . During this 
period his electrical experimentation continued at 
home. In 1848 he invented the electrical striking 
apparatus for the fire-alarm service which he de- 
veloped with Dr. William F. Channing. In 1853 he 
resumed work on other electrical ideas. His later 
accomplishments included in 1855, discovery of a 
means of duplex and quadraplex telegraphy; in 1856 
he started an e 1 ec t r o t y pi ng business after succeed- 
ing in depositing aluminum e 1 ec t r o 1 y t i ca 1 1 y . In 
1858-59 he invented an incandescent electric lamp. 
Farmer was years ahead of his contemporaries in many 
applications of electrical current. Although his 
electrical patents rivaled Edison's his fame and 
profit did not. This is attributed to his tendency 
to continually plunge into unknown territory rather

(48) No patent for this device has been uncov-

existence of an annunciator. Therefore annunciators 
were available, although probably not very wide- 
spread by March 1861.

(61) The 1861 booklet mentions two variations in the 
application and usage of the system. First, "as a means of 
communicating to a stable or other outbuilding, it 
is superior to any and all other means used. ' The 
simple touch of a small spring, arranged in your 
sitting-room, or any, or several parts of the house, 
rings the bell at the stable." (Holmes, A Treatise , 
35) "Every door and window of the stable without 
regard to distance, can be, and is often connected 
with this same Bell in the sleeping room. Any 
person wishing some means to communicate with the 
coachman at the stable, cannot find a better or more 
economical method." (Holmes, A Treatise , 47).

(67) In the patent Whiting states, "I am aware 
that an apparatus has been employed as a burglar- 
alarm in which a single electric circuit was em- 
ployed in connection with the windows and doors of a 
building, and so arranged that the opening of any 
one of them should close the circuit and sound an 
alarm. Such apparatus, however, furnished no indi- 
cation of the whereabouts of the window or door so 
opened, and the proprietor was left to search 
through the whole house for the intruder, who was 
himself perhaps alarmed and enabled to escape. My 
invention had for its object to produce a house- 
alarm which shall not only alarm the proprietor or 
guardian of the house on the intrusion of a burglar, 
but shall at the same time indicate to him the part 
of the house attacked, that his attention may be 
immediately directed to the particular room where an 
entry has been attempted or effected; and this I 
accomplish by the employment of a series of electro- 
magnetic circuits (one for each distinct room or 
portion of the house to be guarded) in connection 
with an indicator for indicating the portion of the 
house attacked." Whiting goes on to describe a drop annun- 



284 



ciator where a small shield covers a letter assigned 
to a particular room, when the alarm is sounded the 
armature is thrown back by its spring and the letter 
indicating the room is exposed to view.

listed as Alarms. Cock appears with an occupation 
listed as Treasurer although he shows a business

had a staff of 600 expert messengers and 50 private 
policemen. It has 21 central stations and 42 manag-

(81) By 1887 there were about twenty companies offer- 
ing district messenger services. Most employed 
"District Telegraph" as part of their corporate name 
and some used the name American District Telegraph

(90) These seven houses were brought to the 
attention of the author through different means. 
Lockwood-Mathews , where the author volunteered for a 
number of years, was the catalyst for this entire 
undertaking. Responses from a query published in 
the APT Communi que identified several houses: Ar- 
mour-Stiner Octagon, Maish, and Wilderstein. Jean 
Wolf, a fellow student and co-worker came across 
Beechwood and the Bowne house. And, finally the 
Fraser house was located as a result of the 1868 
pamphlet listing.

According to Holmes (Jr.) the electrical bell used 
in the system was originally made by Charles Wil- 
liams. In 1876 Holmes opened a machine shop for the 
exclusive manufacture of all Holmes's electrical 
instruments and appliances. Therefore, in order for 
this bell to be original, or nearly original, Stan- 
ley and Patterson of New York City would need to

Charles T. Mathews" [transcribed copy]. Lockwood-

full diary excerpt reads as follows, "an incident 
that second summer was interesting as we had a most 
unpleasant experience of a robbery. We had a number 
of people in the house and were playing bowls down- 
stairs. A fierce and noisy storm raged outside. My 
school friend, Dora Merrell, was visiting me, and as 
I wanted her to be very comfortable I gave up my 
room and dumped all my jewelry into a bureau drawer 
on the opposite side of the house. As I stepped 
from my door for dinner, I saw Dora was simply 
gowned in black. I had on a light blue dress and a 
very valuable medallion of diamonds, turquoise and 
pearls, a gift of Father's, and a necklace of tur- 
quoise to represent forget-me-nots given by Mother. 
Realizing the bad taste of outshining one's guests, 
I stepped back, took them off, and threw them into 
the drawer. While we were bowling Father went to 
his room and hearing someone try to open the con- 
necting door between his bathroom and the Oriental 
room, he called out "That door is locked, go around 
the other way." The burglar delighted at such information

turned and rushed into the side of the house where I 
had moved next to Lillie. Just as I was saying 
goodnight to Dora in her room Lilly came and asked 
for a candle. Instantly I felt something was wrong 
and asked twice before she answered "Someone has 
entered the house and taken everything from my top 
drawer and Will wants to go thru the rooms to see if 
he is in hiding." "Oh!" I said, "all my jewelry is 
there." I flew over to find everything gone. I was 
deeply ashamed for Father had told me to lock up all 
valuable things as this house was like a "Light set 
on a Hill" close to the Post Road between New York 
and Boston. I had always intended to do so but alas! 



(103) Gordon William Fulton, "The Bowne House, 
Flushing, New York: A Historic Structure Report" 
(Master's thesis, Columbia University, 1981), 19-29. 

(104) "The Bowne House, Flushing, New York", 
page reported that prior to 1860, the house was 
equipped with "modern innovations, being heated by a 
furnace and illuminated by gas." Because no "Par- 
sons" are listed on Holmes's 1861 subscriber lists 
it is assumed that an alarm system, while available, 
was not among the added innovations. 

(105) Fulton, "The Bowne House," 168. 

(106) The rooms on the second floor are the 
residence of the caretaker, as well as staff office 
space. Therefore there was limited access to the 
floor area due to placement of furniture and floor 
coverings. Visual inspection indicated at least 
limited presence of floor wires on this floor. 

(107) Holmes, A Treatise , 40. 

(108) Since my first visit in 1990, work has 
been done to replace some of the floorboards. An 
attempt has been made to replicate the original 
wiring patterns.
